Abstract
Provided is a camera actuator including a fixing frame, a first moving frame movable in a first direction, a second moving frame movable in a second direction orthogonal to the first direction, a lens unit movable in a third direction orthogonal to the first direction and the second direction, a first driver moving the first moving frame in the first direction, a second driver moving the second moving frame in the second direction, and a third driver moving the lens unit in a third direction. Further, the third driver includes a driving source portion formed by a first piezoelectric element and a second piezoelectric element lengthened and shortened by energization and attached to each other in a direction orthogonal to a lengthening-and-shortening direction, and an abutting portion abutting against the lens unit and moving in an elliptical trajectory according to deformation of the driving source portion.
