摘要：
A camera is provided which includes a dust-proofing member that has a substantially circular or polygonal plate-shape, and that includes a transparent portion at an area having at least a predetermined length in a radial direction from the center thereof, the transparent portion being opposed to the front of the optical device at a predetermined interval. A member for vibration is annularly arranged at a peripheral portion of the dust-proofing member, and applies vibrations to the dust-proofing member. And a sealing structure is arranged to constitute a space portion that is substantially sealed at a portion formed by opposing the image pick-up device and the dust-proofing member by sealing the space portion at peripheral portions of the image pick-up device and the dust-proofing member.
