The purpose is to facilitate the adjustment of the size of a light emitting region of a lens structure. A lens structure for a vehicle light body includes a light emitting part and a base. The light emitting part includes an introduction reflective surface which causes light from the base to completely reflect as parallel light to the Z− direction, and a back-side reflective surface arranged to the Z direction in the light emitting back surface. Each back-side reflective surface has a normal direction sloping relative to the Z direction, and causes the parallel light from the introduction reflective surface to completely reflect to the Y+ direction. The light emitting surface emits light from the back-side reflective surface.
