To provide a combined power generator using a solar battery and wave power, because although there are many types of power generation using wave power, rocking by waves is used mostly therefor and the scales thereof are small, and thus the power generation is used for a marker lamp or the like.

The solar battery 3 is attached to the upper portion of a floating body 1. A power generation storage system 6 and a charging apparatus 7 are installed inside of the floating body 1. A rope 14 is attached to the bottom of the floating body 1, inserted in a waterproof box 10 fixed on the bottom of the sea, and wound around a pulley 16 connected to the generator 18. Further, a moving pulley 19 located below the pulley 16 is wound, thereby fixing the rope to the inner wall of the waterproof box 10 or a strut separately provided. When the floating body 1 is lifted by wave or transversely swept away by the wind, the rope 14 is pulled up. Thereby, the pulley 16 is rotated, and the blades (or turbines) of the generator 18 are rotated to generate electricity.
