PROBLEM TO BE SOLVED: To provide a capacitor circuit which can be remarkably reduced in a continuity resistance component. SOLUTION: A first circuit 13 which is a series combination of a capacitor 11 and an NMOS transistor 12, and a second circuit 16 which is a series combination of a capacitor 14 and an NMOS transistor 15, are formed in a parallel connection on a semiconductor substrate, Due to this structure, the continuity resistance component of the impedance viewed from terminals 17, 18 can be remarkably reduced when the MOS transistors 12, 15 are in a conducting state.
