Abstract
A mechanism enabling reduction of the size of a structure for mounting an image pickup device without affecting the amount of movement of an optical system even when screw insertion holes of a sensor plate are arranged closer to the optical axis. The sensor plate of an image pickup apparatus is mounted to a lens barrel with screws, and includes an attachment surface to which the image pickup device is attached and contact surfaces which are fixed to the lens barrel. The attachment surface is protruded from the contact surfaces. By bringing the attachment surface to the lens barrel in the optical axis direction, the device has an image pickup surface positioned with respect to the lens barrel in the optical axis direction. The sensor plate has an opening formed between the attachment surface and each contact surface, for absorbing deformation of the sensor plate.
