PROBLEM TO BE SOLVED: To easily configure the capacitor of high voltage specifications proper to a high breakdown-strength inverter circuit on a substrate. SOLUTION: The capacitor for the high voltage inverter circuit is constructed on the insulating substrate 1. The capacitor for the high voltage inverter circuit has an electrode 11 fitted on the wiring surface 1a of the substrate 1, the electrode 12 fitted on the same surface of the substrate 1 while being adjoined to the electrode 11 and the electrode 13 fitted on the part surface 1b of the substrate 1 while being opposed to the electrodes 11 and 12. In the capacitor, the electrode 13 has fixed width W3 and length L3, and is opposed to the electrode 11 at one end section 13c in the length L3 direction while being opposed to the electrode 12 at the other end section 13d. According to the configuration, the portions of the substrate 1 placed among the electrodes 11 to 13 form dielectric layers, and a series-capacitor structure in which either of the electrode 11 and the electrode 12 is used as a storage electrode and a counter electrode while the electrode 13 is used as an intermediate electrode can be configured.
