A camera module shoots a satisfactory image by suppressing the adherence of water droplets to a part in a light transmitting cover through which imaging light is transmitted. Provided are an outer casing (4) comprising a housing (2) having an opening and a light transmitting cover (3) for closing the opening; and a camera module (31) arranged inside the outer casing. A part of the light transmitting cover is provided as a transmission window (23a) through which imaging light incident on the camera module is transmitted, a fluid flow part (43) having a flow path of fluid to be blown onto the transmission window is provided, and a backflow prevention mechanism (47) is provided in the fluid flowing part.
