Camera modules shoot 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 and to which fluid is blown, and a fluid flowing part (43) having a flow path of the fluid and connected to a fluid supply source (40) is provided. The fluid flowing part has a first supply part (44) and a second supply part (45) which are branched into two or more, and the fluid supplied to the first and second supply parts is blown onto different transmission windows for different camera modules.
