摘要：An optical scanning device of the invention includes: a substrate; torsion barportion which is connected to the substrate; a mirror portion which is supported by thetorsion bar portion; a drive source which causes the substrate to oscillate; and a lightsource which projects light onto the mirror portion, where the mirror portion resonates

and vibrates in accordance with a vibration imparted to the substrate by the drive source,and the direction of reflection light from the light projected onto the mirror portionfrom the light source changes in accordance with the vibration of the mirror portion, anda spring constant in a longitudinal direction of the torsion bar portion supporting themirror portion is distributed along the longitudinal direction of the torsion bar portion.
