PROBLEM TO BE SOLVED: To obtain a lens driving device capable of accurately moving a lens support body. SOLUTION: The lens driving device 1 is equipped with the lens support body 7; a coil 10 fixed on the outer circumference side of the lens support body 7; a yoke 3 having a nearly U-shaped cross section and possessing an aperture on its inner periphery side; and a magnet 13 provided inside the yoke 3. The lens support body 7 is equipped with a flange part 21 on its outer circumference. A coil-attaching part 23 and a yoke-butting part 25 are provided on the flange part 21, and the coil-attaching part 23 is positioned inside the yoke 3. The coil 10 is stuck and fixed at the coil-attaching part 23, and the flange part 21 moves the aperture of the yoke 3 and regulates the movement of the lens support body 7, by making the yoke butting part 25 of the flange part 21 abut against the aperture end of the yoke 3. An adhesive clearance part 27 that is recessed more in the lens-moving direction than to the yoke-butting part 25 is formed at the flange part 21. COPYRIGHT: (C)2006,JPO&NCIPI
