1. A lens driver, characterized in that, comprising:
a lens holder configured for holding a lens;
a first coil which is arranged on an outer circumference of the lens holder so that the lens holder acts towards a direction parallel to a direction of an optical axis of the lens;
a plurality of magnets which are arranged on the outer circumference of the first coil and face the first coil at a defined distance;
a magnet holder which is located on the outer circumference of the lens holder and which holds the plurality of magnets;
an upper spring and a lower spring which connect the lens holder and the magnet holder;
a plurality of second coils which are arranged at positions corresponding to the plurality of magnets and spaced from the plurality of magnets at a defined distance in the direction of the optical axis, and which make the lens holder act towards a direction orthogonal to the direction of the optical axis of the lens; and
a fixation part for fixating the plurality of second coils from a side of the second coils opposite to the plurality of magnets, on which holes are opened at positions corresponding to winding starting terminals of the plurality of second coils;
an opening size of each hole is greater than a winding size of a corresponding one of the plurality of second coils, and the winding starting terminal of the second coil passes through the hole and extends from an inner circumference of the second coil to an outer circumference of the second coil without increasing a height of the fixation part plus the second coil.
