PROBLEM TO BE SOLVED: To provide a leaf spring for a lens driving device, which provides stable performance by equalizing N spring parts in size even when manufacturing them in a pressing method by which the manufacturing time can be reduced in comparison with an etching method.SOLUTION: A leaf spring 1 for a lens driving device comprises N split leaf spring pieces 11 formed to be of the same shape, and each of the N split leaf spring pieces 11 comprises a split frame piece 12 forming a part of a frame part 2 of the leaf spring 1 for a lens driving device and a spring piece 13 extending from the split frame piece 12 toward the inner periphery to form a spring part 3 of the leaf spring 1 for a lens driving device. The split frame pieces 12 are arrayed in a circumferential direction in a state of partially overlapping with each other, to form an annular frame part 2 and include step parts 12d and 12e by which N spring parts 3 are placed on the same plane though the split frame pieces 12 partially overlap with each other. |
