The objective of the present invention is to provide an LED projector capable of using cooling means such as a heat-radiating fan efficiently, and allowing size reduction. For this purpose, the LED projector is configured from an appropriate power source circuit, and is sequentially arranged with: a panel-shaped light-projecting part obtained by forming a light-projecting surface whereon a plurality of LED elements are arranged; a heat sink having a plurality of radiator plates on the back surface of the panel-shaped projection part; and a cooling fan for sending air toward the center portion of the heat sink. In the LED projector, the plurality of radiator plates from the heat sink are disposed in such a manner as to radiate from the center portion to the periphery. The center portion of a surface whereby the heat sink radiator plates are joined to one another protrudes toward the air-sending fan, and has a curved surface portion oriented from the center portion to the periphery.
