1. An image stabilizing unit, comprising:
- a base member in which a long side of the base member is at least twice as large as a shorter side of the base member in a direction perpendicular to an optical axis;
a movable compensation member which can displace an image forming position by moving in a plane perpendicular to the optical axis; and
two drive units which respectively move the movable compensation member in different directions, wherein the different directions in which the two drive units respectively move the movable compensation member are inclined to a direction which connects the two drive units and an optical axis center of the movable compensation member and are respectively inclined to the long side of the base member.

Abstract
There is provided an image stabilizing unit 1 small in size in one direction perpendicular to an optical axis, including, on a base member 2, a movable compensation member 5 which can displace an image forming position by moving in a plane perpendicular to an optical axis Z, and two drive units 6, 7 for displacing the movable compensation member 5 in the directions of R and S which are different from each other for 90 degrees, wherein the directions in which the drive units 6, 7 respectively move the movable compensation member 5 are inclined 45 degrees to a direction X which connects the drive units 6, 7 and the optical axis center Z of the movable compensation member 5.
