To provide a lighting device capable of restraining temperature rise of a light-emitting section at the time of irradiating laser beams.

The headlight (lighting device) 1 includes: a semiconductor laser 2 for emitting laser beams; and the light-emitting section 5 containing phosphor sintered body made by sintering oxynitride phosphor and emitting fluorescence by receiving the laser beams emitted from the semiconductor laser 2. Thus, the headlight 1 can restrain temperature rise of the light-emitting section 5 at the time of emitting the laser beams with high output and high density since it can quickly radiate heat generated in the light-emitting section to the outside.
