1. A piezoelectric power generation device for generating power by applying distortion deformation to piezoelectric ceramics members formed in plate shapes;

  • said piezoelectric power generation device comprising;

    the piezoelectric ceramics members each including two plate shaped piezoelectric ceramics elements whose polarization is set to the same direction and an extremely thin metallic electrode interposed between the piezoelectric ceramics elements, the piezoelectric ceramics member being formed in a laminar shape by uniting the piezoelectric ceramics elements to the metallic electrode; and

    cushion materials for supporting central parts or both end parts of one surfaces of the piezoelectric ceramics members, wherein the piezoelectric power generation device has a soft support structure in which the natural oscillation of the piezoelectric ceramics members is hardly transmitted to other structural members.
