Abstract: Disclosed is an underwater camera, including: a casing having an accommodation space for a camera module; a connector coupled to a first side of the casing and transferring a signal output from the camera module to a controller; a lens connected to the lens and coupled to a second side of the casing in a manner that a periphery portion of the lens is embedded in the second side of the casing; a sealing means coupled to the second side of the casing and preventing water from entering into the casing and from reaching the lens; and a valve coupled to the first side of the casing and having a hose connected to a sealed space provided between the sealing means and a surface of the second side of the casing, thereby discharging air from the sealed space and supplying an inert gas into the sealed space.
