1. An actuator device comprising:
a support part;
a first movable part;
a second movable part formed in a frame shape and arranged so as to surround the first movable part, wherein a coil is provided to the second movable part;
a pair of first connecting parts arranged on both sides of the first movable part in a first axis direction parallel to a first axis and connecting the first movable part to the second movable part so that the first movable part can swing around the first axis; and
a pair of second connecting parts arranged on both sides of the second movable part in a second axis direction parallel to a second axis orthogonal to the first axis and connecting the second movable part to the support part so that the second movable part can swing around the second axis,
wherein the second movable part includes a pair of first connection portions positioned on both sides of the first movable part on the first axis and connected to the pair of first connecting parts, a pair of second connection portions positioned on both sides of the first movable part on the second axis and connected to the pair of second connecting parts, and a pair of first portions, wherein one of the pair of the first portions is connected to one of the pair of the first connection portions and one of the pair of the second connection portions and extends in a direction inclined with respect to the first axis direction and the second axis direction, and the other of the pair of the first portions is connected to the other of the pair of the first connection portions and the one of the pair of the second connection portions and extends in a direction inclined with respect to the first axis direction and the second axis direction,
in each of the pair of first portions, a distance between an inner edge of the first portion and the coil is greater than a distance between an outer edge of the first portion and the coil when viewed in a direction orthogonal to the first and second axes.
