Optical image stabilization apparatus that provides image stabilization by using movable member and optical apparatus

An optical image stabilization apparatus comprising:

• a movable member configured to hold an optical element;
• a base member configured to hold the movable member movably in a movement direction that intersects an optical axis of the optical element;
• a first position detector and a second position detector configured to detect a position of the movable member relative to the base member in a direction of a first detection axis and a direction of a second detection axis that are different from each other and parallel to a plane including the movement direction, respectively;
• and
• a first driving unit and a second driving unit configured to drive the movable member relative to the base member in a direction of a first drive axis and a direction of a second drive axis that are different from each other and parallel to the plane, respectively,
• wherein an angle formed by the first detection axis and the second detection axis is not a right angle,
• wherein at least one of the direction of the first detection axis and the direction of the second detection axis is different from each of the direction of the first drive axis and the direction of the second drive axis,
• wherein an intersection of the first drive axis and the second drive axis is closer to a center of gravity of a movable unit including an element fixed to the movable member among the optical element, the movable member, the first driving unit, and the second driving unit, than an intersection of the first detection axis and the second detection axis, and
• wherein on a plane parallel to the movement direction, a product of a distance between an intersection of the first detection axis and the second detection axis and the optical axis of the optical element, and a distance between an intersection of the first drive axis and the second drive axis and the center of gravity is 3.3 mm2 or less.
