PROBLEM TO BE SOLVED: To provide a lens driving device capable of accurately driving a lens holder in the optical axis direction.SOLUTION: A lens driving device 1 includes a lens holder 200, inner magnetic bodies 112A, 112B, guide parts, and a coil member 400. The lens holder 200 has a cylindrical part 202 for holding a lens, and magnets 208 to 218 positioned outside the outer peripheral surface of the cylindrical part 202 while being separated from the outer peripheral surface of the cylindrical part 202. The inner magnetic bodies 112A, 112B are positioned between the cylindrical part 202 and the magnets 208 to 218. The guide parts guide the lens holder 200 in the optical axis direction OA of the lens. The coil member 400 is positioned outside the outer peripheral surfaces of the magnets 208 to 218 while being separated from the outer peripheral surfaces of the magnets 208 to 218. The guide parts are positioned so as to sandwich the inner magnetic bodies 112A, 112B between the magnets 210 to 214 and themselves. |
