Abstract

A linear light source (), which emits light by causing light to propagate in a linear material () in which incoming light can be propagated, includes: a light emitting device (), provided on a side of one end of the linear material (), which emits light so that the light enters the one end of the linear material (); and a light receiving device (), provided on a side of the other end of the linear material (), which detects the light which has propagated in the linear material (). With the configuration, it is possible to provide: a linear light source in which an abnormal condition, such as breaking of a linear material, can be detected; and an electronic apparatus including the linear light source.
