Abstract
An actuator includes a swing portion swingable about a first axis orthogonal to a central axis extending vertically and about a second axis orthogonal to the first axis and intersecting the central axis. An angle detector includes a pair of first angle detection elements above a non-magnetic structure and extending in the second axis direction with the first axis interposed therebetween when viewed from the central axis direction, and a pair of second angle detection elements extending in the first axis direction with the second axis interposed therebetween. Each of the first angle detection elements and each of the second angle detection elements include a columnar magnetic structure between the swing portion and the non-magnetic structure in the central axis direction, and a detection coil along the outer periphery of the magnetic structure.
