Abstract
In order to expand the surface area of a reflective layer, the space between adjacent turns of a drive coil, which is wound a plurality of turns on a peripheral edge front surface of the principal surface of a movable portion which, being inside a frame-formed support substrate, is connected to the support substrate by torsion bars, is filled and flattened with a smoothing layer, thereby adopting a configuration such that the reflective layer can also be provided in the region of the upper surface of the drive coil.
