Abstract:
The invention provides an image blur correction apparatus including: a tabular base portion; a movable portion that holds an image pickup device and that is movable with respect to the base portion; and a voice coil motor that has a permanent magnet arranged on a face of the base portion that faces the movable portion, and a coil arranged in a region of the movable portion facing the permanent magnet, and that generates a force that moves the movable portion by an electromagnetic force. The base portion is composed of a magnetic body. A tabular second magnetic body portion composed of a magnetic body that, when viewed from the incident light axis direction, occupies a region surrounding the external shape of the permanent magnet is arranged on the base portion side of the permanent magnet.
