PURPOSE:To prevent a control circuit from malfunctioning by attenuating noises which penetrate into an inverter through an outer wiring or the like led into the inverter with a simple structure small in number of required components. CONSTITUTION:Cylindrical bodies 2 formed of magnetic material such as ferrite cores or hollow square bodies of two-split structure are fixed in the vicinity of an outer wiring lead-in opening 1a or a terminal pad 5 of a control board 4 of an inverter body case 1, and an outer wiring 3 is led into the inverter case 1 through the center of the cylindrical body 2 or a control pattern is made to penetrate the center of the hollow square body. |
