<P>PROBLEM TO BE SOLVED: To provide a power generator, electrical apparatus, and portable clock, having excellent generation efficiency. <P>SOLUTION: A power generator comprises a first electrode member 11 that functions as an electrode, and a second electrode member 13 that is disposed to oppose to the first electrode member 11 and has an electret film 12. At least one of the first electrode member 11 and the second electrode member 13 is structured to be elastically deformable. By relatively moving the first electrode member 11 and the second electrode member 13 along the opposing surface, an overlapping area between the first electrode member 11 and the electret film 12 of the second electrode member 13 changes. <P>COPYRIGHT: (C)2013,JPO&INPIT |
