In a direct projector type vehicle lamp 10 using a rectangular light emitting surface 12A as a light source, the bottom edge of the light emitting surface 12A is arranged such that it extends along the horizontal line that is perpendicular to the optical axis Ax and such that the point O on the bottom edge is placed on the optical axis Ax. The rear surfaces of first and third lens regions Z1, Z3 of the lens 14 are formed with a Fresnel lens on the basis of the first reference line L1 and the rear surfaces of second and fourth lens regions Z2, Z4 of the lens 14 are formed with a Fresnel lens on the basis of a second reference line L2, thereby forming a horizontal cutoff line. An end portion of each of the lens regions Z1-Z4 is configured as an extended area Zla-Z4a which extends into the adjacent lens region, thereby forming an oblique cutoff line. |
