1. An optical device comprising:
a support portion;
a movable unit; and
a pair of torsion bars disposed on both sides of the movable unit on a first axis and connecting the support portion and the movable unit to each other so that the movable unit can swing around the first axis,
wherein the movable unit includes a main body portion at which an optical function unit is disposed, a ring-shaped portion formed in a ring shape to surround the main body portion when viewed from a predetermined direction perpendicular to the first axis, two connection portions connecting the main body portion and the ring-shaped portion to each other, and a rib portion provided to the main body portion,
each of the two connection portions includes two connection regions that are separated from each other by a space and the each of the two connection region connects the main body portion and the ring-shaped portion to each other, and
the rib portion includes four extending portions radially extending between a center of the main body portion and the four connection regions respectively when viewed from the predetermined direction.
