Abstract
An image projection apparatus for projecting an image using light includes a light source configured to emit the light; and an operating unit configured to allow a user to operate the image projection apparatus, the operating unit being disposed above the light source when viewed from a placement surface on which a main body of the image projection apparatus is placed. The image projection apparatus also includes a first flow path in which air flows through the light source; and a second flow path different from the first flow path, the second flow path being formed between the light source and the operating unit.
