Abstract
A first substrate is formed with a lens, a plurality of beams for supporting the lens, and a first electrode provided on the plurality of beams. A second substrate is formed with second electrodes at location opposed to the plurality of beams through gaps. A voltage control circuit applies voltage between the first electrodes formed on the plurality of beams and the second electrodes to apply the electrostatic force to the plurality of beams to generate bending, thereby changing a tilting direction of the lens.
