ABSTRACT:
A camera is provided which includes a dust-proofing member having a substantially circular or polygonal plate-shape and a transparent portion at an area having at least a predetermined length in a radial direction from a center of the dust-proofing member. The transparent portion is opposed to a front of an optical device at a predetermined interval, and an interval of an equivalent optical path length of at least 5 mm is provided between a surface of the dust-proofing member and the photoelectrically converting surface of the image pick-up device. And a sealing structure portion is arranged at a portion formed by opposing the image pick-up device and the dust-proofing member. The sealing structure seals a space portion that is substantially sealed at peripheral portions of the image pick-up device and the dust-proofing member.
