This vehicle lamp comprises: a light source (2); and a reflector (3) that includes a diffusion/reflection surface (3a) which reflects light (L) projected from the light source (2) while diffusing said light towards a front surface. In a cross-section in at least one direction along the optical axis (AX) of the light (L) projected from the light source (2), the diffusion/reflection surface (3a) has a curved shape that forms a curve which matches the directionality of the light (L) projected from the light source (2).
