Therefore, the photoelectric conversion module 10a can be protected. Further, since the photoelectric conversion device 1a includes the connecting portion 20 configured to satisfy the relationship of a ≧ b, the width of the connecting portion of the connecting portion 20 is secured to some extent, and the coupling portion of the connecting portion 20 has high durability. Sex can be ensured.

Further, when d ≧ b ≧ d / 2, the effect can be further enhanced, which is more preferable.

Further, it is preferable that the main body portion 30b has a thickness equal to or larger than the thickness of the photoelectric conversion module group 50 at the time of folding.
