A vehicle lamp comprising: a light source, and a compound optical lens that emits light of the light source toward the front side, wherein, the compound optical lens is an integrally molded lens having an incidence surface, an emission surface, and a shade part, the incidence surface receiving light, the emission surface emitting the light from the incidence surface toward the front side, the shade part being disposed between the incidence surface and the emission surface, the compound optical lens includes: a first reflector surface that is disposed above a top line of the shade part on an upper side of the of the incidence surface and which reflects a light forming a first diffused light distribution pattern of a low-beam light distribution pattern toward the emission surface; and a second reflector surface that is disposed below the top line of the shade part on a lower side of the incidence surface and which reflects a light forming a condensed-light distribution pattern of the low-beam light distribution pattern toward the emission surface, the shade part forming a substantially triangular recess on an inner side of the compound optical lens from the lower side in the vertical direction at a position between the incidence surface and the emission surface of the compound optical lens, the position of the apex of the triangular recess forming the top line that matches the shape of a cut-off line of the low-beam distribution pattern, the top line being formed so that the portion forming the upper side of the cut-off line is positioned at the rear focal point or in the vicinity of the rear focal point of the emission surface; and the width of the first reflector surface is larger in a width of a vehicle width direction at a position where the first reflector surface and the second reflector surface are adjacent to each other. a light source, and a compound optical lens that emits light of the light source toward the front side, wherein, the compound optical lens is an integrally molded lens having an incidence surface, an emission surface, and a shade part, the incidence surface receiving light, the emission surface emitting the light from the incidence surface toward the front side, the shade part being disposed between the incidence surface and the emission surface, the compound optical lens includes: a first reflector surface that is disposed above a top line of the shade part on an upper side of the of the incidence surface and which reflects a light forming a first diffused light distribution pattern of a low-beam light distribution pattern toward the emission surface;
