Abstract

A capacitor circuit includes two ceramic capacitors that are connected in series. The two ceramic capacitors each have a ferroelectric layer interposed between conductive layers and have substantially identical direct-current bias characteristics such that an electrostatic capacitance during application of a voltage, which is half of a rated voltage, is larger than the electrostatic capacitance during application of the rated voltage higher than the voltage.
