PROBLEM TO BE SOLVED: To provide a lens driving device capable of improving the density of a magnetic flux generated by a driving magnetic and passing through a driving coil, protecting a leaf spring without making the shape of the leaf spring connecting a moving body and a fixed body complicated, and simplifying a structure.SOLUTION: A lens driving device 1 includes: a moving body 2; a fixed body 3; a driving mechanism 4; and a leaf spring 5. The driving mechanism 4 includes: a driving coil 15 fixed to the moving body 2; and a driving magnet 17 fixed to the fixed body 3, and oppositely disposed to the driving coil 15 on the outside in a radial direction of a lens. The fixed body 3 includes: a yoke member 13 which has an end plate portion 13a formed by a magnetic material and disposed so as to cover one end surface of the driving magnet 17 in an optical axis direction, and an inside yoke portion 13b disposed on the inside of the driving coil 15 in a radial direction; and a cover member 10 formed separately from the yoke member 13a by the magnetic material, and covering outer peripheral sides of the moving body 2, the driving mechanism 4, and the leaf spring 5. |
