1. A lens driving apparatus, comprising:
a holder being a rectangle and having a central opening and four sides;
a cover coupled with the holder and having an opening corresponding to the central opening of the holder;
a carrier assembled to a lens assembly having an optical axis, wherein the carrier is disposed in the cover and is movable along a direction parallel to the optical axis;
a sensing magnet coupled with the carrier;
a printed circuit board disposed near to one of the four sides of the holder in an upright form with respect to the holder;
a position sensor disposed on the printed circuit board and corresponding to the sensing magnet for detecting a displacement parallel to the optical axis of the sensing magnet;
a coil disposed on an outer surface of the carrier; and
at least one driving magnet disposed in the cover and corresponding to the coil;
wherein the holder further comprises a plurality of first metal terminals and a plurality of second metal terminals, each of the first metal terminals is outwardly extended away from the central opening of the holder, and each of the second metal terminals is fixedly connected with the printed circuit board;
wherein the first metal terminals are disposed only on one of the four sides of the holder, a number of the first metal terminals is at least two, the second metal terminals are disposed on at least one of the other three sides of the holder, a number of the second metal terminals is at least two, and the two of the first metal terminals are electrically connected with the two of the second metal terminals.
