摘要： In order to provide a lens module having a simply structured lens drive mechanism that is capable of stabilizing the moving speed of an optical lens system, the lens module has a structure wherein a lens holder (to which no illustrated optical lens system is mounted) (6) that mounts a moving body (5) attractable to a magnet (4) is mounted on a housing (7) using guide pins (8), and wherein one side of a piezoelectric ceramic element (3) is adhered to the magnet (4) in the displacement generating direction (longitudinal direction) of the piezoelectric ceramic element 3, and the other side thereof is adhered to the housing (7), with the moving body (5) and the magnet (4) being attracted by a magnetic force. The lens holder (6) supporting the moving body (5) is movably supported by the guide pins (8). The magnetization direction of the magnet (4) is substantially orthogonal to an optical axis direction of the optical lens system and is a radial direction of the optical lens system. The lens drive mechanism moves the lens holder (6) along the optical axis direction by vibrating the magnet (4) using vibrations generated by the piezoelectric ceramic element (3), and by driving the moving body (5) with the vibrations of the magnet (4) as a driving force.
