  The second light emitting unit 14 is composed of a semiconductor light emitting element having a horizontal width 14x and a vertical length 14y. Therefore, as shown in FIG. 2B, the second light emitting unit 14 has a horizontal width 14x and a vertical length 14y, and has a vertically long shape extending in the optical axis O direction. The semiconductor light emitting element constituting the second light emitting unit 14 is, for example, a light emitting diode (LED), and is mounted with a light source in a state in which the light emitting surface is directed substantially vertically downward and the irradiation axis is orthogonal to the optical axis O of the lamp unit 10. It is mounted on the insulating substrate 11 provided on the portion 54 (see FIG. 1).

A second light distribution pattern P2 that can be formed is formed. Therefore, as in the past, it is possible to form a lamp unit capable of combining light distribution patterns whose shapes are significantly different from the combination of the DRL light distribution pattern and the high beam light distribution pattern. Thereby, multifunctionalization and space saving of a vehicle lamp can be achieved at a high level.

  The first light distribution pattern P1 can be used not only as a fog light distribution pattern but also as a part of a low beam light distribution pattern or a part of a high beam light distribution pattern.
