Claim:
1. An optical device comprising: a movable section capable of swinging about a first axis; a frame body section capable of swinging about a second axis crossing the first axis; a first shaft section configured to connect the movable section and the frame body section; and a light reflection plate fixed to the movable section and provided with a light reflecting section having light reflectivity, wherein the movable section includes the light reflection plate fixed to a base, a center of gravity of the light reflection plate being shifted from a center of gravity of the base and the center of gravity of the base being aligned with the first axis, in plan view from a thickness direction of the light reflection plate, the center of gravity of the light reflection plate is shifted from the first axis, the light reflection plate is formed in a shape symmetrical with respect to an axis through the center of gravity of the light reflection plate and parallel to the first axis, and the light reflection plate is fixed to the base such that the axis through the center of gravity of the light reflection plate is not aligned with the first axis through the center of gravity of the base.
