1. A lens driving device, comprising:
an autofocus movable part;
an autofocus fixing part disposed spaced apart from the autofocus movable part;
an autofocus driving section being configured to move the autofocus movable part in an optical-axis direction with respect to the autofocus fixing part;
an optical image stabilization movable part including the autofocus movable part, the autofocus fixing part, and the autofocus driving section;
an optical image stabilization fixing part disposed spaced apart from the optical image stabilization movable part; and
an optical image stabilization driving section being configured to sway the optical image stabilization movable part in a plane orthogonal to the optical-axis direction with respect to the optical image stabilization fixing part,
wherein the autofocus movable part includes a first position detection magnet,
wherein the optical image stabilization fixing part includes a first hall element to be provided facing the first position detection magnet in the optical-axis direction and to detect a position of the autofocus movable part in the optical-axis direction, and
wherein the first position detection magnet is a single-pole magnet having a cylindrical shape and magnetized in a height direction of the first position detection magnet, and is disposed such that the height direction coincides with the optical-axis direction.
