PROBLEM TO BE SOLVED: To provide a camera module and a camera which enable movement of an image sensor and also enable large lenses with large-aperture lenses, zooming or the like to be mounted.SOLUTION: An actuator unit comprises: a movable joint part to which one end of an imaging element is secured and which is movable in response to back-and-forth movement; a parallel link mechanism part, one end of which is mounted on the movable joint part while the other end of which is secured, and which holds the imaging element at a target position synchronized with movement of the movable joint part; and a needle, one end of which is joined so as to allow transmission of displacement motion in relation to a joined area between the movable joint part and the one end of the parallel link mechanism part, and which is displaced by a displacement corresponding to a level of applied driving voltage, to cause the imaging element to move back and forth between a first position and a second position in the optical axis direction. |
