Abstract
Provided is a projector capable of suppressing deterioration of a portion of a projection portion irradiated with a laser beam while improving brightness. This projector is formed to deviate optical axes of laser beams emitted from a plurality of laser beam generation portions respectively from each other so that the laser beams emitted from the plurality of laser beam generation portions respectively do not concentrate on one point of a projection portion.
