Abstract
An output circuit device for detecting and converting signal charge transferred thereto from a charge transfer section of a CCD into a signal voltage his constructed such that a gate oxide film of a driving side MOS transistor of a first stage source follower which receives signal charge is formed as a thinner film than gate oxide films of the other MOS transistors in the same circuit to reduce the 1/f noise.
