1. A camera actuator, comprising:
a fixed-side member;
a movable-side member arranged apart from the fixed-side member in a direction orthogonal to an optical axis and holding a lens part;
a first lens driving actuator that displaces the movable-side member in at least a prescribed direction;
an elastic support member supporting the movable-side member on the fixed-side member so as to allow displacement of the movable-side member in at least a first direction which is a direction of the optical axis and a second direction orthogonal to the first direction and extending in a third direction orthogonal to the first direction and the second direction; and
a damping member arranged between the movable-side member or a member fixed to the movable-side member, and the fixed-side member or a member fixed to the fixed-side member,
wherein:
the fixed-side member includes bottom part and a pair of side wall parts extending from both end parts of the bottom part to direction orthogonal to an optical axis;
the movable-side member includes a holding part that holds the damping member;
the holding part includes a recess and a protrusion that are provided adjacent to each other;
the damping member is arranged between the holding part a member fixed to the side wall parts;
a first end parts of the damping member in the third direction are attached to the holding part; and
a second end parts of the damping member in the third direction are attached to the member fixed to the side wall parts.
