To provide a vehicular lamp having a high light utilization efficiency and moreover giving a novel appearance, in which a reflection surface of a reflector is divided radially with an optical axis as a center.

The vehicular lamp is provided with a semiconductor light source 10 arranged on an optical axis Ax of the vehicular lamp 1, a reflector 40 including a plurality of reflection surfaces 41 divided radially with the optical axis As as a center, and boundary parts 43, and a lens cap 30 covering the front side of the light source 10. The lens cap 30 includes a side lens part 32 for projecting toward the reflector 40 a side direction emission light L2 out of the light advancing frontward from the light source 10, and this side lens part 32 refracts the side direction emission light L2 so as to avoid the boundary parts 43.
