In the case of a projection type vehicle lamp, even when the projection lens is composed of a plurality of lenses, it is possible to form a light distribution pattern having a high uniformity. The projection lens (20) is composed of two lenses (22, 24) arranged on an optical axis (Ax) extending in the front-rear direction of the vehicle. In this case, the rear main surface (Pr) of the projection lens (20) is formed by a convex curved surface having a large curvature as compared with a spherical surface (S1) having a rear focal point (F) as its center. As a result, the coma aberration extending toward the inner side (the optical axis side) is generated on the imaging surface of the projection lens (20); as a result, in the light distribution pattern formed by the light emitted from the projection lens (20), blurring caused by the coma aberration can form blurring with a tail extending toward the outside of the light distribution pattern, thus improving the uniformity of the light distribution pattern.
