摘要 An image projection apparatus (1) for projecting an image using light includes a light source (61) configured to emit the light; and an operating unit (83) configured to allow a user to operate the image projection apparatus (1), the operating unit (83) being disposed above the light source (61) when viewed from a placement surface on which a main body of the image projection apparatus (1) is placed. The image projection apparatus (1) also includes a first flow path in which air flows through the light source (61); and a second flow path different from the first flow path, the second flow path being formed between the light source (61) and the operating unit (83).
