Abstract
An image projection apparatus includes: an image forming unit that forms an image using light from a light source; a projecting optical unit that forms a projected image of the image formed by the image forming unit; and an outer housing that houses the image forming unit and the projecting optical unit. The image forming unit and the projecting optical unit are provided in an order from a setting surface of the outer housing. A width of the outer housing in a direction perpendicular to a projection surface is larger at a position where the projecting optical unit is provided than at a position where the image forming unit is provided.
