PROBLEM TO BE SOLVED: To provide inverter power supply equipment equipped with low loss having the effect of saving energy by adopting a capacitor for voltage doubler rectification with low loss, excellent in anti-ripple resistance performance. SOLUTION: A capacitor which is an metallized film element formed by winding a both-side metallized film, 1 to 3μm in thickness, having an aluminum electrode 2 with its film resistance value between opposite electrodes of 5 to 30Ω/cm2 and a non-metallized laminated film 4 and is filled with high-viscosity insulation oil with a kinematic viscosity at 100 deg.C of 90 mm2/s or higher is used as a capacitor for voltage doubler rectification in inverter power supply equipment, and that by, inverter power supply equipment with a low loss contributing to energy saving is obtained.
