Abstract

A lens body includes a first reflecting surface totally reflecting entered light, a second reflecting surface totally reflecting at least some of the light totally reflected at the first reflecting surface, and a light emitting surface emitting light passed through forward, wherein the first reflecting surface includes an elliptical spherical shape with reference to a front-focal point and a rear-focal point disposed parallel with each other in the forward/rearward direction, the rear-focal point disposed in a vicinity of a light source, the light emitting surface has a first leftward/rightward emission region and a second leftward/rightward emission region adjacent to the first leftward/rightward emission region in a leftward/rightward direction, the first leftward/rightward emission region refracts the entered light in a direction approaching a forward/rearward reference axis, and the second leftward/rightward emission region refracts at least some of the entered light in a direction getting away from the forward/rearward reference axis.
