Claim Text:
1. A thin-film capacitor device for discharging a thin-film capacitor for use in a DC circuit, wherein said thin-film capacitor comprises a first electrode made of electro-conductive material, a second electrode made of electro-conductive material and positioned to be faced with the first electrode, and a dielectric layer formed to be interposed between the first electrode and the second electrode, between the first electrode and the dielectric layer and between the second electrode and the dielectric layer there being electron collector layers, each of which includes an electron collector constituted of microparticles made of metal, semiconductor material or an electro-conductively surface-modified ceramic, said device comprising a charging circuit charging said thin-film capacitor, and a discharge circuit, said discharge circuit being of a hybrid type for temporarily storing charge upon receiving DC current from said thin-film capacitor that has been charged while voltage becomes lowering, and for supplying DC current in a state of a DC/DC inverter having a base voltage remaining so that a discharge effect continues until an amount of storage in said thin-film capacitor completely runs out.
