摘要： A subject is to provide a high-performance linear light emitter in which an angle distribution of exiting light in a peripheral direction is optimized, and which can radiate light from a side peripheral surface with high directivity and without loss. There is an aspect of making a line width of a light reflecting layer appropriate in a translucent rod-shaped body which has a light incident portion at least at one end thereof and which has, on a peripheral side surface running along an axial direction, the light reflecting layer reflecting incident light from the light incident portion. An aspect, in which an angle of a light reflecting groove, surface roughness, or the like is made appropriate in a translucent rod-shaped body which has a light incident portion at least at one end thereof and which has, on a peripheral side surface running along an axial direction, a light reflecting groove reflecting incident light from the light incident portion, is used.
