Abstract

A vehicle headlamp includes a reflector having plural reflecting surfaces arranged in a left-right direction, and n light sources which are arranged in the left-right direction and emit light toward any one of the reflecting surfaces. At least two adjacent light sources are provided as a common light source which emits light toward a same reflecting surface. n illumination patterns which illuminate different regions in the left-right direction are formed by light emitted from the n light sources, respectively, and are taken as a first to n-th illumination patterns in this order in the left-right direction. At least half of areas of illumination patterns of an immediately-following number and an immediately-preceding number overlap each other in the left-right direction. Focal lengths of the plural reflecting surfaces are set such that adjacent illumination patterns which do not overlap each other are formed by light emitted from the common light source.
