Abstract:
An image stabilization device includes a movable portion including an image pickup lens and a VCM driving portion configured to drive the movable portion relative to a fixed portion, the image stabilization device including: a position detection element arranged on the movable portion; and paired position detection magnets arranged at positions facing the position detection element and arranged on the fixed portion; wherein the paired position detection magnets are a first magnet and a second magnet arranged so that different magnetic poles face a surface of the position detection element; the first magnet and the second magnet are arranged in order along a direction away from an optical axis of a light flux incident on the image pickup lens; and magnitudes of densities of magnetic fluxes reaching the surface of the position detection element from the first magnet and the second magnet, respectively, are mutually different.
