<P>PROBLEM TO BE SOLVED: To provide a piezoelectric power generation device capable of efficiently generating power by movement in a compression direction, the movement having a relatively small amount of displacement such as earthquake vibration and engine vibration, and furthermore, to provide an antivibration device including the piezoelectric device. <P>SOLUTION: A piezoelectric power generation device 1 includes at least one piezoelectric element 2 having two sheet-like electrodes 3 arranged in parallel and a dielectric 4 disposed between the two sheet-like electrodes 3. A non-compressive elastic material 5 having an elastic modulus less than that of the piezoelectric element 2 is bonded on at least an entire one surface of an outer side surface in the thickness direction of the piezoelectric element 2. In addition, an antivibration device includes the piezoelectric power generation device 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
