The second step is completed when SF6 gas is introduced and raised to 1 atm or higher, for example, 1.5 atm, and maintained for an appropriate time, for example, about 30 minutes. The third step is completed when the leak valve B3 is opened, the gas pressure of SF6 is lowered to atmospheric pressure, and then closed. The fourth step is completed by opening the valve B4, injecting a synthetic resin such as epoxy resin, heating the resin around the outer periphery of the capacitor element, and sealing SF6 gas into the gap inside the capacitor element. A desired capacitor can be manufactured through the first to fourth steps as described above. Three effects of the invention: The method for manufacturing a capacitor of the present invention uses a gas having an electrically insulating property, for example, in the third step. This manufacturing method allows the corona start voltage of the capacitor to be significantly increased (approximately 200°6 or more) by setting the pressure of the SF6 gas to atmospheric pressure.
