PROBLEM TO BE SOLVED: To provide a lens module capable of providing a stable moving speed by stabilizing a displacement quantity of a magnet of a driver, and to provide the lens module superior in assembling productivity, with a structure capable of correcting the magnetization direction when easily assembling even when the direction of the magnet in the driver is varied. SOLUTION: This lens module has a housing 51, the driver, a lens holder 41, an optical lens 10 supported by or integrated into its holder, and a moving body 31. The driver is composed of a weight member 71, a piezoelectric ceramic element 11 having one end fixed to the weight member 71 and the magnet 21 adhered to its other end. The weight member 71 is fixed to the housing 51, and the moving body 31 is composed of a construction material adsorbable to the magnet 21, and is integrated into the lens holder 41. The magnet 21 is vibrated by vibration generated by the piezoelectric ceramic element 11, and the lens holder 41 is moved by driving slidingly the moving body 31 with the vibration of the magnet 21 as driving force.
