PROBLEM TO BE SOLVED: To provide a lens driving device for enhancing fixing strength of a first case body and a second case body combined in an optical axis direction, and suppressing passage of an electromagnetic wave between the inside and outside of the device in a comparatively simple configuration. SOLUTION: The lens driving device 1 includes a movable body 2 for holding a lens, a drive mechanism for driving the movable body 2, and the first case body 11 and the second case body 12 mutually fixed to be combined in the optical axis direction. The first case body 11 is formed of a magnetic material and arranged in an object side so as to surround the drive mechanism. The second case body 12 is formed of a resin material and arranged in an anti-object side. An attaching recess 12b for attaching the lens driving device 1 to portable equipment is formed on the outer peripheral face of the second case body 12. An extending part 11e extended to the anti-object side is formed at a position avoiding the attaching recess 12b so as to be overlapped from the outside on the outer peripheral face of the second case body 12 in the first case body 11.
