<p>PROBLEM TO BE SOLVED: To downsize an image projector, and to provide the image projector capable of excellently cooling a power source substrate.SOLUTION: The image projector includes: a control part for controlling light emission of a light source 61; an electric power stabilizing part for supplying stable electric power to the light source 61; and a power supply part for supplying the electric power to at least one of the control part and the electric power stabilizing part. One or both of the power supply part and the electric power stabilizing part are divided into multiple substrates (80a, 80b). The light source 61 is arranged on a normal line of one surface of the multiple substrates, and the multiple substrates (80a, 80b) form a flow path which does not have at least a surface nearest to the light source 61.</p> |
