  • Image stabilization unit, lens apparatus, and image pickup apparatus
    Patent number: 11974043
    Abstract: An image stabilization unit includes an optical element, a lens barrel configured to hold the optical element, a magnet, and a fixing member. The image stabilization unit further includes a sensor that detects a position of the lens barrel by sensing magnetism of the magnet, and a flexible substrate connected to the sensor. The flexible substrate includes a sensor mounting portion mounted to the sensor, a movable-side holding portion held by the lens barrel, and a fixed-side holding portion held by the fixing member. The movable-side holding portion and the fixed-side holding portion are located in such a manner as to overlap the sensor mounting portion in an optical-axis direction.
