PROBLEM TO BE SOLVED: To provide an output circuit of a CCD solid-state image sensor which supports high-speed reading while saving power. SOLUTION: The output circuit includes: an initial stage source follower circuit to which image signals that are extracted through floating diffusion are supplied; and a final stage source follower circuit to which image signals that are amplified by the initial stage source follower circuit are supplied. The final stage source follower circuit includes a driver MOS transistor and a load MOS transistor, each of which includes a P-type MOS transistor. COPYRIGHT: (C)2011,JPO&INPIT
