PROBLEM TO BE SOLVED: To provide a lens driving device, preventing the occurrence of shift in a lens optical axis even when a mover and a support are connected to each other using two spring members. SOLUTION: In this lens driving device 1, a spring support member 11 includes a frame-like part 115 and four columnar parts 119 extending from the frame-like part 115 in the same direction along the lens optical axis direction L, an object side spring member 14y is connected to a part corresponding to the root of the columnar part, and an image side spring member 14x is connected to the tip of the columnar part 119. The object side spring member 14y and the image side spring member 14x are connected to the spring support member 11 at four places in the periphery of the lens optical axis L. Among four places, two places opposite to each other with the lens optical axis L interposed between them are located at point symmetry positions about the lens optical axis, and the other two places opposite to each other with the lens optical axis interposed between them are located at point symmetry positions about the lens optical axis.
