PROBLEM TO BE SOLVED: To provide a laminated power generation moored body having a piezoelectric film which can obtain electric energy from a variety of kinds of ocean energy such as tidal currents, ebb and flow, and waves.SOLUTION: A laminated power generation moored body 10 is integrally laminated and constituted of: a piezoelectric film 11 having a power generation function for generating an electric charge by being polarized according to distortion generated by a mooring force; an electrode film formed on the piezoelectric film 11; and substrates 12a, 12b composed of flexible elastic materials which are laminated on the electrode film. The laminated power generation moored body generates power by expansion and contraction deformation and bend deformation of the piezoelectric film 11, and has a three-layer or five-layer structure in which the substrates 12a, 12b are laminated so as to sandwich the piezoelectric film 11. The piezoelectric film 11 is formed of a polymer piezoelectric film made of polyvinylidene fluoride. |
