POWER GENERATION ELEMENT, POWER GENERATION DEVICE, POWER GENERATION UNIT, AND POWER GENERATION ELEMENT INSTALLATION METHOD

摘要

PROBLEM TO BE SOLVED: To achieve improvement of power generation performance and power generation efficiency of piezoelectric power generation, which uses a piezoelectric polymer, advantageously in terms of cost using a simple structure.SOLUTION: A power generation element 1 includes a porous resin layer 20 that includes a plurality of pores 20A and contains a fluorine resin as a main component, with electric energy being obtained through a change in thickness of a resin film. It is preferable that the plurality of pores 20A include a communication hole. It is preferable that the main component of the porous resin layer 20 is a polymer containing tetrafluoroethylene as a monomer unit. A power generation device 5 has a structure where an elastic body is laminated on the power generation element 1.
