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 (103) on which an electronic component is mounted is secured to a housing (102) by a metal spacer (108) and a screw (104). A noise control member (100) mainly composed of an insulation substance is disposed between the metal spacer (108) and the substrate (103). A first conductive film is formed on the metal spacer-side of the noise control member (100), and a second conductive film is formed on the substrate-side of the noise control member (100). A resistance member (101) 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.
