A pair of upper and lower incidence surfaces are formed on a rear face of a translucent member disposed to cover three light-emitting elements. On upper and lower sides of the incidence surfaces are formed a pair of reflection surfaces for causing light emitted by the light-emitting elements and having entered the translucent member to internally reflect forward. Each of the incidence surfaces is formed from a cylindrical convex-curved surface extending horizontally. Each of the reflection surfaces is formed from a parabolic cylindrical curved surface whose focal line passes through a virtual image point of each of the light-emitting elements formed by the corresponding incidence surfaces. By the above configuration, light emitted by the light-emitting elements is caused to internally reflect in such a manner as to diffuse in the horizontal direction, and not to diffuse in the vertical direction, thereby exiting forward from a pair of exit surfaces.
