Abstract
An optical scanner includes: a movable section which has a light reflecting member with a light reflecting surface and which is rotatable around the central axis of rotation; at least a pair of movable beams extending from the movable section along the light reflecting surface; a displacement section which is connected to the movable beams and has a through hole including two fixed surfaces crossing each other; two driving beams which extend from the displacement section along a surface direction of the light reflecting surface so as to be perpendicular to the movable beams; a support section connected to each of the driving beams; a driving section which drives the displacement section; and a permanent magnet which is inserted in the through hole and is fixed to the two fixed surfaces.
