PROBLEM TO BE SOLVED: To provide a resin complex and a radial noise suppressing substrate which effectively suppresses the noise radiated from an electronic part and an electronic circuit board.;SOLUTION: The resin complex is provided in which a synthetic resin contains a magnetic body. A resin complex 12 is used to constitute an electronic part and electronic circuit board in which a complex dielectric constant real- number part εr' and a complex relative magnetic permeability real-number part μr' are 6 at a frequency band 200 MHz to 10 GHz while the attenuation is 2 dB/cm or higher.;COPYRIGHT: (C)2002,JPO
