An image projection apparatus (1) includes a light source (4) that emits light; an image generation element (10) to generate an image; an optical radiation system (7, 8, 9) to irradiate the image generation element using the light emitted from the light source (4); an optical projection system (3b) to project the image generated by the image generation element onto a projection face; a color wheel (5), disposed on a light path of light emitted from the light source (4), to separate the light while being rotated; a light tunnel (6) to guide light exiting from the color wheel (5) to the optical radiation system (7, 8, 9); and a shield (20) disposed in a space between the color wheel (5) and the light tunnel (6) in a light radiation direction from which the light from the light source (4) is irradiated. The shield (20) covers at least a part of a side of the light tunnel (6) facing a rotation center of the color wheel (5). |
