Abstract:
An optical scanner includes: a base portion; a light reflecting portion that reflects light; a connection portion that connects the base portion and the light reflecting portion; and a shaft portion that supports the base portion in a swingable manner, wherein the light reflecting portion is disposed so that a geometrical center of the light reflecting portion is separated from a geometrical center of the base portion in a plan view, and wherein the light reflecting portion includes a center of gravity adjusting portion that performs adjustment so that a distance between the geometrical center of the base portion and a center of gravity of the light reflecting portion in the plan view becomes smaller than a distance between the geometrical center of the light reflecting portion and the geometrical center of the base portion in the plan view.
