Abstract
A linear light source (20), which emits light by causing light to propagate in a linear material (11) in which incoming light can be propagated, includes: a light emitting device (12), provided on a side of one end of the linear material (11), which emits light so that the light enters the one end of the linear material (11); and a light receiving device (21), provided on a side of the other end of the linear material (11), which detects the light which has propagated in the linear material (11). 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.
