Abstract
A light guiding body of this invention comprises a light incident surface arranged on one end side of a light guide member, a light reflecting surface arranged on another end side of the light guide member opposite to the light incident surface across the light guide member, and a light emitting surface, arranged on a side surface of the light guide member between the light incident surface and the light reflecting surface, through which light input from the light incident surface into the light guide member passes to outside, in which the light guide member is formed as a solid body and at least a part of the light guide member is made from light scattering guide material which contains light scattering particles.
