Projector

The utility model provides a projector, which can improve the cooling efficiency of a heat source and realize miniaturization. The projector includes: a light source; one light modulation element that has a first surface that intersects the optical path of the light from the light source, and modulates the light from the light source on the basis of an image signal; an optical path changing element that changes the optical path of the light emitted by the light modulation element; a projection lens that projects the light whose optical path has been changed by the optical path changing element; a housing that accommodates the optical modulation element and the optical path changing element; a first fan that is disposed between the housing and the optical path changing element and that causes the first airflow to flow in a first direction on the first surface; a second fan that is disposed between the housing and the optical path changing element and that causes a second airflow to flow in a second direction d
