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.

Linear light source and electronic apparatus

In a semiconductor laser apparatus, semiconductor laser devices are mounted on a loading face of a radiation base portion produced from a radiation material in a mount board, and the radiation base portion and a cap portion constitute an envelope surrounding the semiconductor laser devices. Further, the radiation base portion and interconnections formed on and an extending face of the radiation base portion constitute an external connection terminal. Therefore, heat generated by the semiconductor laser devices is efficiently transferred to the radiation base portion produced from a radiation material. Further, constituting the external connection terminal allows a leadless configuration to be implemented. Thus, a semiconductor laser apparatus which is sufficient in radiation characteristics and is capable of supporting a low-profile specification is provided.
