<p>A vibration power generation body (1) is primarily composed of an electret dielectric (3), electrodes (5a, 5b), and spacers (7). The electrodes (5a, 5b) are positioned on both surface of the electret dielectric (3) in such a manner as to face the electret dielectric (3). Both surfaces of the electret dielectric (3) are charged by charges that are opposite to each other. Furthermore, the electret dielectric (3) is constructed with a porous material (e.g., a resin foam). In other words, minute pores (4) are formed inside the electret dielectric (3).</p> |
