Position detecting apparatus and image stabilization apparatus to which position detecting apparatus is applied

摘要

A position detecting apparatus includes: a fixed member in which a magnet is disposed, a movable member including a movable barrel in which a coil and an optical element are disposed, the movable barrel being driven in a direction perpendicular to a direction along an optical axis of the optical element with respect to the fixed member by a VCM driving section, and a magnetism detecting member disposed in the movable member, the magnetism detecting member detecting a change in a magnetic flux density of the magnet at a time when the movable member is driven. The magnetism detecting member is disposed, in a plane perpendicular to a direction along the optical axis, in a position where a magnetic flux density of the coil does not affect the change in the magnetic flux density due to the magnet when an electric current is fed to the coil.
