Abstract

An optical scanning device includes a mirror and a drive beam. The drive beam includes a piezoelectric portion. The piezoelectric portion is partitioned by a plurality of first grooves into a plurality of piezoelectric bodies. The piezoelectric bodies are reduced in length in an X-axis direction as the piezoelectric bodies approach one end side connected to an anchor. The piezoelectric bodies are reduced in length in the X-axis direction as the piezoelectric bodies approach the other end side connected to a link beam.
