PROBLEM TO BE SOLVED: To provide an image projection device which improves heat radiation, while using a plurality of lasers for a light source.SOLUTION: An image projection device 10 is an image projection device 10 including first and second light source parts 11 including one or more light sources, first and second reflection parts 14 reflecting light from the first and second light source parts 11, a synthesis part 16 synthesizing the light reflected by the first and second reflection parts 14, and a projection lens 20 projecting the light synthesized by the synthesis part 16. The first light source part 11 includes at least one light source located on one side with respect to a plane including the optical axis of the projection lens 20 and passing through the first and second reflection parts 14 and emitting the light toward the plane from one side. The second light source part 11 includes at least one light source located on the other side with respect to the plane and emitting the light toward the plane from the other side. |
