<P>PROBLEM TO BE SOLVED: To provide a noise filter that is provided with a wiring connection structure in which the contact resistance of a connection terminal is small and which is excellent in a vibration resistance property and sealing performance and can improve a heat radiation effect. <P>SOLUTION: In the noise filter in which a filter circuit 11 is resin-molded in a resin case 12, a nut member 14 is insert molded and embedded in an internal and external terminal connection part 13 of a resin case, a fixing bolt 20 inserted through inner side connection terminals 17 and 18 connected from an inner side of the resin case to a filter circuit side is screwed into the nut member, the inner side connection terminals are adhesively sandwiched between the head of the fixing bolt and the inner end face of the nut member, the fixing nut 21 is screwed into a point part of the fixing bolt projecting toward the external part of the resin case from the nut member by going through an outer side connection terminal 19 connected to an outer side circuit, and the outer side connection terminal is adhesively sandwiched between the fixing nut and the outer end face of the nut member to thereby make the inner side connection terminals conduct to the outer side connection terminal through the nut member. <P>COPYRIGHT: (C)2009,JPO&INPIT |
