Abstract:
This electric device comprises electrical components (1, 60), an electrical component support unit (21), and an outside frame (90). An interior space (92) is formed between the electrical component support unit and the outside frame, the electrical components are installed in the internal space, and gas is enclosed in the internal space at a water vapor pressure of 0.60 Pa or less. In electric devices in which electrical components such as electrolytic capacitors (60), etc., are disposed in a closed space, this makes it possible to prevent the occurrence of condensation on the wall surfaces, etc., of the closed space, and to prevent damage to the electrical components due to air pressure.
