Abstract
On an upper surface of a fixed substrate, a plurality of strap-shaped base electrodes are arranged in parallel to each other. On each of the base electrodes, an electret is formed. The electret has a width wider than the width of each base electrode, and the electret covers an exposed surface of the base electrode. A movable substrate is disposed in parallel to and facing the surface of the fixed substrate where the electrets and others are formed. The movable substrate is movable relatively to the fixed substrate. On a facing surface of the movable substrate, strip-shaped counter electrodes are each formed so as to face each base electrode.
