Abstract
This lens driving device comprises an autofocus (AF) driving unit and a shake correction driving unit, wherein a shake correction support member has a pair of power supply suspension wires and a pair of signal suspension wires. While an AF movable unit includes a position detecting magnet, an AF fixation unit includes an AF power source line, a signal line, a coil power source line, and an AF control unit. The AF control unit includes a hole element, and a coil control unit which controls current passing through an AF coil part, and an AF circuit board on which the hole element and the coil control unit are mounted. As a result of contact between a lens holder and a base which has rigidity higher than that of a coil substrate, movement of the AF movable unit toward a formed image in the optical axis is restricted.
