Abstract
A lens driver which has a high driving effectiveness and a compact form, and which does not require a precise assembling and a assembling time. It comprises: a lens holder which holds the lens; a first coil which is arranged on outer circumference of the lens holder so that the lens holder acts towards a direction orthogonal to direction of the optical axis of the lens; a magnet which is arranged on the outer circumference of the first coil and which faces the first coil at a defined distance; a magnet holder which is arranged on the outer circumference of the lens holder to hold the magnet; an upper spring and a lower spring which connect the lens holder and the magnet holder; a second coil which is arranged at a position corresponding to the magnet and spaced from the magnet at a defined distance in the direction of the optical axis, and which makes the lens holder act towards a direction orthogonal to direction of the optical axis of the lens; and a fixation member for fixating the second coil, on the fixation part, holes are opened that can be passed through by the end of the second coil, and the opening size of the hole is greater than the winding size of the second coil, and the end of the second coil passes through the hole and extends from the inner circumference of the second coil towards the outer circumference.
