Abstract
An optical scanner, including a frame member; a pair of connection members near a coupling end with the frame member; a pair of elastic members connected with the frame member by the connection members; a mirror substrate supported by the pair of elastic members, the mirror substrate having a bending rigidity outward from the rotational axis for each area in accordance with a bending moment caused by oscillation, the mirror substrate having a slit at both connection ends with the pair of elastic members; and a piezoelectric element provided on each of the connection members, the piezoelectric element generating a torque for driving the mirror substrate oscillatable back and forth around the pair of elastic members as a torsion rotational axis.
