LENS DRIVING DEVICE

PROBLEM TO BE SOLVED: To provide a lens driving device which can prevent breaking of a coil. SOLUTION: The lens driving device 1 is provided with: a mobile object (sleeve 13, etc.) that is movable in a light axis direction while holding a lens; a support body (back yoke 11, etc.) that supports the mobile object in a movable manner in the light axis direction; a magnetically activated mechanism equipped with a coil 18 and a magnet 17, and spring members (first and second plate springs 14, 15) that are placed between the mobile object; and the support body and controls the move of the mobile object in the light axis direction. The spring members are composed of several spring pieces 151, 152 that are electrically divided and a front end and the back end of the winding coil of a coil 18 are electrically connected to different spring pieces 151, 152, respectively, among the several spring pieces. Several pins 136 that project in the light axis direction L are installed in line in the periphery direction on the mobile object near a part where the front end and the back end of the winding coil are electrically connected.
