PROBLEM TO BE SOLVED: To provide a camera device having simple structure and small volume, and consecutively adjusting a focus. SOLUTION: The camera device is provided with: a lens module including a lens barrel and a lens received in the lens barrel; a magnetic member including at least one magnet mounted around an outer peripheral surface of the lens barrel; and a frame body configured to house the lens module and the magnetic member, and also is provided with a printed circuit board coil and an elastic member fixed around an outer peripheral surface of the lens module. The elastic member is provided with at least one elastic piece, which includes a movable end connected with the lens module and a fixed end opposite the movable end. In the process where the lens module moves by action force between a magnetic field generated by applying an electric current to the printed circuit board coil and the magnet, the movable end of the elastic piece also moves, following the lens module, thereby deforming the elastic piece.
