However, the above-mentioned Patent Documents 1 and 2 have the following problems. In both of the absorbers of Patent Documents 1 and 2, the length in the width direction is not constant but varies. Therefore, when the absorbent article is worn, the widthwise length of the absorbent body that stands up against the side of the penis differs. In a region where the length of the absorbent body in the width direction is relatively short (for example, the crotch side region in the absorbent articles of Patent Documents 1 and 2), the width of the absorbent body is relatively short, so it is easy to fit around the penis. . On the other hand, in a region where the length of the absorbent body in the width direction is relatively long (for example, the ventral region in the absorbent articles of Patent Documents 1 and 2), the width of the absorbent body is relatively long and the penis accommodation space is large. There was a risk of leakage due to excessive deviation. In particular, at the position where the length of the absorbent body in the width direction is maximum, the space for accommodating the penis becomes too large, which tends to increase the risk of leakage.

The present invention was made in view of these problems, and provides an absorbent article for men that can secure a space for accommodating the penis, prevent the space from becoming too large, and prevent leakage due to slippage. The purpose is to provide.

The deformation guide portion has a cross deformation portion that intersects with an imaginary line connecting outer edges of the absorbent body at a maximum width position where the length in the width direction of the absorbent body is longest. The cross deformation portion extends along the front-rear direction.

The absorbent article for men according to aspect 2 includes: a front-back direction extending toward the crotch side and ventral side of the wearer; a width direction perpendicular to the front-back direction; an absorbent body that retains body fluids; and an absorbent body that induces deformation of the absorbent body. and a deformation guiding section. The length of the absorbent body in the width direction is varied. The deformation guide portion has a cross deformation portion that intersects with an imaginary line connecting outer edges of the absorbent body at a maximum width position where the length in the width direction of the absorbent body is longest.

The intersecting deformation portion 71 may be any deformation guiding portion 70 that intersects at least one of the virtual lines FL. The deformation guide section 70 may be configured only of the intersecting deformation section 71 (the deformation guide section 70 that intersects with the imaginary line), or may include only the deformation guide section 70 other than the intersecting deformation section 71 (the deformation guide section that does not intersect with the imaginary line FL). 70). Further, the cross deformation portion 71 may be linear or curved. The curved deformation guide portion 70 may have a portion where the curvature changes, for example, a portion extending in the width direction W (a portion parallel to the width direction W, and a portion inclined at an angle of less than 45 degrees with respect to the width direction W). (including the configuration) and a portion extending in the front-rear direction L. In addition, if the cross deformation part 71 is constituted by an aggregate of a plurality of deformation guide parts 70 arranged discontinuously, the dimensions of each deformation guide part 70 (each element arranged discontinuously) If the gap between each deformation guide part 70 is short, an integrated intersecting deformation part 71 is formed, and if the gap between each deformation guide part 70 is larger than the dimension of each deformation guide part 70, the said gap It is assumed that separate intersecting deformation portions 71 are formed by dividing at .

Note that the configuration extending in the front-rear direction L is a concept that includes not only a configuration parallel to the front-rear direction L but also a configuration that intersects the front-rear direction L at an angle of 45 degrees or less. According to the absorbent article 1 according to the first embodiment, since the cross-deforming portion 71 extends in the front-back direction L, the fold base point of the cross-deforming portion 71 extends in the front-back direction L, and the absorbent body 30 is folded in the width direction W. easy. Therefore, the absorbent body 30 is easily deformed into a shape that covers the outer periphery of the penis, and the fit can be improved.

The absorbent article 1 according to the second embodiment is characterized in that the length of the cross-deformed portion 71 in the front-rear direction L is longer than the length of the cross-deformed portion 71 in the width direction W.
