In a waterproof housing for storing a camera, a transparent window for causing light to be refracted toward a nearer side is provided on at least part of a portion that covers a front surface of the camera. Accordingly, a direction of travel of light from the camera is bent toward an optical axis of a photographic lens, and hence a photographic subject can easily get light. The light is, for example, auxiliary light used for automatic focusing.
