An image capturing apparatus includes a projector and a camera. The projector includes a light source unit and a projector lens barrel unit. The camera includes a camera lens barrel unit. As viewed in a direction that is orthogonal to a direction toward which an optical axis of the projector travels, the projector lens barrel unit is arranged to overlap with the camera lens barrel unit, and the light source unit is arranged so as not to overlap with the camera. A duct via which air to be blown to the light source travels is arranged in such a manner that the air travels in a direction orthogonal to the direction toward which the optical axis of the projector travels.
