摘要： PROBLEM TO BE SOLVED: To provide a device for suppressing the jamming caused by electromagnetic waves, which can effectively suppress unwanted jammings by electromagnetic waves, without needing anew wiring such as a grounding conductor, etc., in an electric/electronic apparatus using a single-phase two-line system of AC power source.
SOLUTION: This device, which suppresses unwanted electromagnetic waves from being generated in the electric/electronic apparatus operation, being connected to a general commercial power source in an office, a home, or the like, has a polarity-determining means, which automatically determines the neutral wire (neutral side) at the grounding potential in the single-phase power source of the commercial power source and the live wire (hot side) of an active part and a grounding point connection means, which connects by a capacitor and a resistor, the neutral wire of the single-phase power source determined by the polarity determining means with the conductive part or the conductive casing on the ground side of the electric/electronic apparatus operating, being connected to the single-phase power source.
