An image projection apparatus is disclosed which is capable of reducing noise when airflows from plural flow paths are taken in into a fan and exhausted therefrom. The apparatus comprises a first flow path (B) through which a first airflow (W1, W2) for cooling a light source (1) passes, a second flow path (A) through which a second airflow (W4, W5) for cooling constituent parts (8, 10) other than the light source passes, a fan (18) which exhausts air introduced from the first and second flow paths to the outside of the apparatus, a third flow path (27b) which introduces a third airflow (W6) to an exhaust area between the light source and the fan in the first flow path, and a light-shielding member (19, 20) which is provided in the exhaust area and shields the light from the light source.
