Abstract
A noise current passing through a substrate on which an electronic component is mounted is suppressed in a housing, to provide a malfunction of an electronic device. A substrate () on which an electronic component is mounted is secured to a housing () by a metal spacer () and a screw (). A noise control member () mainly composed of an insulation substance is disposed between the metal spacer () and the substrate (). A first conductive film is formed on the metal spacer-side of the noise control member (), and a second conductive film is formed on the substrate-side of the noise control member (). A resistance member () is disposed between the first conductive film and the second conductive film. A noise current introduced from the housing to the substrate can be suppressed by the resistance member.
