PROBLEM TO BE SOLVED: To suppress reset feedthrough noise to variations of potential of a diffusion layer, etc. SOLUTION: In this CCD device, an electric charge transfer register of CCD structure is connected to an electric charge detection part 3 via an output gate 2, a reset gate 4 is provided between the electric charge detection part 3 and a reset drain 5, an output gate pulse with the opposite phase to a reset pulse applied to the reset gate 4 is applied to the output gate 2, a dummy electric charge detection part 7 is provided, and an amplitude adjustment circuit 8 which controls amplitude of an output gate pulse applied to the output gate 2 based on detection results of the potential of the diffusion layer of the dummy electric charge detection part 7 is provided.
