Abstract: An actuator includes a first driving beam that is connected to an object to be driven and includes multiple first beams extending in a direction orthogonal to a first predetermined axis, ends of each adjacent pair of the first beams being connected to each other via one of first turnaround parts such that the first driving beam forms a zig-zag bellows structure as a whole; first driving sources formed on first surfaces of the first beams; and ribs formed on second surfaces of the first beams at positions that are closer to the first predetermined axis than the first turnaround parts. The first driving sources are configured to move the first driving beam and thereby rotate the object around the first predetermined axis.
