The present invention provides an unmanned watercraft capable of sufficiently cooling equipment that generates a large amount of heat, capable of cooling such equipment without using energy in the watercraft, and capable of improving mean time between failures (MTBF) of a cooling device. An unmanned watercrafthas a cooling structure CS for cooling a central processing unit CPUfor image recognition and a central processing unit CPUfor control that constitute a central processing unit CPU as a heat-generating body. The cooling structure CS includes a waterproof containerthat accommodates the heat-generating body (an insulating envelope that surrounds the heat-generating body in an electrically insulated state). The waterproof containeris arranged outside a submerged partof the unmanned watercraftso as to be in contact with water present outside the unmanned watercraft, the submerged partbeing submerged in water.
