In an output circuit for a charge transfer device, a floating diffusion region is connected to a source side gate electrode of a double-gate read-out field effect transistor having its drain side gate electrode connected to the drain of the read-out transistor itself. Thus, the capacitance between the gate of the read-out transistor connected to the floating diffusion region and the drain of the read-out transistor can be made small, so that the total capacitance of the floating diffusion region is correspondingly reduced, with the result that a high detection sensitivity can be realized.
