In a light projecting apparatus including a laser light source, a light projecting apparatus is divided into a laser-light-source module and a light-projecting optical module. In the laser-light-source module NOR laser beams from a plurality of laser light sources are combined by a beam combiner. The laser-light-source module and the light-projecting optical module are connected to each other by an optical fiber in a cable. A laser beam formed by the beam combiner is transmitted through the optical fiber to the light-projecting optical module, received by a fiber receptacle, and projected. In the laser-light-source module NOR a fiber-breakage countermeasure section that detects breakage of the optical fiber and takes countermeasures against the breakage is disposed.
