VIBRATION POWER GENERATOR, VIBRATION POWER GENERATING DEVICE, AND COMMUNICATION DEVICE AND ELECTRIC APPARATUS EQUIPPED WITH VIBRATION POWER GENERATING DEVICE

摘要

A vibration power generator configured from a first substrate (102), a second substrate (103) disposed facing the first substrate, first electrodes (104L, 104R, 106) formed on the first substrate, and second electrodes (105L, 105R, 107) formed on the second substrate, wherein: the first electrodes and the second electrodes hold electric charges having the same polarity; and the first substrate vibrates such that the angle formed from a line connecting the center of the fist electrodes (104L, 104R) with the center of the second electrodes (105L, 105R) and the half line extending in parallel to the main surface of the second substrate from the center of the second electrodes (105L, 105R) towards the still first electrodes (104L, 104R) does not exceed 55 degrees when the first substrate (102) is still or is vibrating.
