Abstract
As imaging devices are miniaturized, and optical devices are miniaturized, lens moving mechanisms are also miniaturized. Thus, position sensors for them are required to be miniaturized and have high accuracy at low cost. A magnet of a pillar shape and a yoke which move in the X axis direction with respect to a magnetic field detection element are provided, and a shape of a cross section of the yoke which is orthogonal to a longitudinal direction of the magnet changes along the longitudinal direction.
