Claim:
1. A noise reduction device comprising: a conductive bar of conductive material; a magnetic material core of magnetic material disposed at surroundings of the conductive bar; a substrate attached to the conductive bar so as to be adjacent to the magnetic material core; a metal tubular portion with a through hole having the conductive bar penetrating therethrough and accommodating the magnetic material core and the substrate therein; a capacitor mounted on the substrate and having a first terminal connected to the conductive bar and a second terminal connected to an inner wall of the through hole; and a blocking unit blocking an opening of the through hole so as to affix the conductive bar with respect to the metal housing and the tubular portion, wherein the tubular portion includes an outer peripheral surface having a screwed engagement part screwedly engaged with the metal housing, the magnetic material core, the substrate, and the capacitor are disposed in the through hole blocked by the blocking unit, and the conductive bar has an outer end that functions as an output terminal.
