PROBLEM TO BE SOLVED: To provide a capacitor which can effectively shield noise generated from a magnetron. SOLUTION: A case of the capacitor is combined with a ground plate in order that electrode insulation pipes integrally formed in the case extend through extending pipes mounted in the ground plate. A pair of electrodes respectively extend through the electrode insulation pipes. A fixing cover is inserted through an upper opening of the case into the case to be disposed over the electrode insulation pipes, of which a connection bar extends through the case so as to come in contact with a screwed hole formed in the ground plate. The extending pipes respectively prevent unnecessary microwave noise generated from the magnetron. A length of the extending pipe is preferably in the range of 5 to 15 mm. Furthermore, the extending pipe and the electrode are made so that a sum of radii of the extending pipe and the electrode is≤5 mm. COPYRIGHT: (C)2003,JPO
