Abrégé

Provided is a capacitor circuit in which parallel resonance caused by plural capacitors which are constituent elements can be prevented to thereby increase the allowable ripple current. A capacitor circuit (1) has a circuit configuration in which a first capacitor line (14) comprising a film capacitor (11) and a second capacitor line (15) comprising a ceramic capacitor (12) are connected in parallel.  An inductance element (13) is inserted into the second capacitor line (15) and connected in series with the ceramic capacitor (12).  The inductance element (13) is set to a value at which the series resonance frequency (f14) of the first capacitor line (14) and the series resonance frequency (f15) of the second capacitor line (15) match.
