Abstract
A line radiation preventing element absorbs undesired radio waves superposed upon a wire or a coaxial cable by use of a magnetic substance, instead of reflection of the undesired radio waves and without increasing the cost thereof. The line radiation preventing element for preventing undesired radio waves superposed upon a wire led out of an electronic appliance from being radiated, has a conductive core wire (2) connected to the wire (5) led out of the electronic appliance; a conductive outer pipe (1) arranged concentrically with the conductive core wire (2), one end of the conductive outer pipe being shorted to the conductive core wire by use of at least one of a shorting plate (3) or an electric capacitance (14) and the other end of the conductive outer pipe being opened; and a magnetic substance (7) arranged between the conductive core wire and an inner wall of the conductive outer pipe.
