Claim 9:
10. An image blur correction device that corrects blur of an image formed in an imaging element by an imaging optical system, the image blur correction device comprising:
a movable mechanism to which an optical component included in the imaging element or the imaging optical system is fixed;
a support mechanism that supports the movable mechanism to be movable in a first direction perpendicular to an optical axis of the imaging optical system; and
a first drive mechanism that generates thrust of moving the movable mechanism in the first direction,
wherein the first drive mechanism includes a first magnetic force generator that is fixed to one mechanism of the support mechanism and the movable mechanism and in which a direction connecting both magnetic poles is parallel to the first direction, and a first coil that is fixed to the other mechanism of the support mechanism and the movable mechanism to face the first magnetic force generator,
in a state in which the movable mechanism is at a reference position where the optical axis of the imaging optical system coincides with a center of the imaging element, a position in the first direction of a center between both magnetic poles of the first magnetic force generator and a central axis of winding of the first coil deviate from each other,
the support mechanism supports the movable mechanism to be movable in the first direction and a second direction perpendicular to the optical axis of the imaging optical system and the first direction,
the image blur correction device comprises:
a second drive mechanism that generates thrust of moving the movable mechanism in the second direction,
the second drive mechanism includes a second magnetic force generator that is fixed to one mechanism of the support mechanism and the movable mechanism and in which a direction connecting both magnetic poles is parallel to the second direction, and a second coil that is fixed to the other mechanism of the support mechanism and the movable mechanism to face the second magnetic force generator, and
in a state in which the movable mechanism is at the reference position, a position of a center between both magnetic poles of the second magnetic force generator in the second direction coincides with a central axis of winding of the second coil.
