Abstract
An optical deflector, including a fixed base; a mirror having a light reflection surface; a pair of elastic support members oscillatably supporting the mirror; and a pair of drive beams formed of a beam-shaped member on which a piezoelectric is fixed, wherein the elastic support members and the drive beams in longitudinal directions are almost orthogonally located and connected with each other, other ends of the drive beams are fixed on the fixed base, the mirror and the pair of elastic support members are cantilevered by the pair of drive beams relative to the fixed base, and bending oscillation of the drive beams causes torsional deformation of the elastic members to rotationally oscillate the mirror.
