PROBLEM TO BE SOLVED: To provide an underwater observation device capable of achieving simplification of laying operation of the underwater observation device at the bottom of sea and recovery operation of the underwater observation device laid down at the bottom of sea, and capable of preventing breaking of a communication line and a wire.SOLUTION: An underwater observation device 10 includes: a communication buoy 11 including an antenna 21, a secondary battery 24, a noncontact charger 26, and a communication device 27; and an observation device body 12 including a noncontact charger 31, a battery, a communication device 34, and a storage tube 37 for housing the communication buoy 11. A swivel 42 arranged in the lower end of the communication buoy 11, and a reel 35 arranged in the observation device body 12 are joined by a high tension cable 41 without a power line, which is wound onto the reel 35. Moreover, the reel 35 is rotated in such a manner that tension is not applied to the high tension cable 41 when the high tension cable 41 is unreeled. |
