To provide a wind turbine generator with a compact structure can cope with winds from multi-directions, installable in a small space, free from influence of a wind direction, can generate power efficiently and can cope with weak to relatively strong winds.
The wind turbine generator is provided with rigid wind receiving blades for generating vibration when receiving a wind force which is formed to be long and folded into two in a width direction, square piezoelectric elements installed on the wind receiving blades for generating power by being bent by the vibration of the wind receiving blades and support bodies provided with a plurality of square piezoelectric elements and the wind receiving blades generate power by winds in two or more directions.
