Abstract
A vibrating mirror comprises a moving mirror configured to deflect a light beam, a torsion bar coupled to the moving mirror and defining a rotational axis of the moving mirror, and a mirror driving part configured to produce a rotational force for causing the moving mirror to oscillate, wherein the torsion bar is coupled to the moving mirror at connecting positions offset from the rotational axis by a distance r/2 in opposite directions so as to satisfy r>A/6, where A is the width of the moving mirror perpendicular to the rotational axis.
