Abstract: 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.

Abstract: A stacked-type capacitor with a fuse function for breaking an abnormal current wherein internal electrodes of a same polarity stacked in a ceramic body are led out to an outer surface of the ceramic body through lead-out electrodes. The lead-out electrodes have end surfaces exposed in the outer surface of the ceramic body. A film electrode for fuse function is formed on the outer surface to overlie the end surfaces of the lead-out electrodes and to be connected to an external electrode formed on the ceramic body. The film electrode is made from metallic powder and/or metallo-organic compound paste. The paste can contain powder of glass forming elements.
