PROBLEM TO BE SOLVED: To obtain a camera shake correction device whose actuator is improved, thereby decreasing mechanical members and achieving miniaturization. SOLUTION: The camera shake correction device includes: a pair of actuators 10x and 10y capable of rotationally displacing independently of each other; a transmission member which converts the rotational displacement of the respective actuators into linear displacement of the supporting members 3 and 4 of an imaging device 1; a detection device which detects camera shake caused when performing the photographing operation of a digital camera; and a control part which drives the respective actuators in accordance with the detected camera shake and displaces the imaging device 1 through the transmission member and the supporting member to correct image blur caused by the camera shake. The actuator 10x comprises a yoke 11x, a coil 12x wound round the yoke, and a permanent magnet 13x arranged proximately to the yoke and rotationally displacing according as the coil is energized.
