Claims

[Scope of Claim for Utility Model Registration] (1) A metal plate for an anode that forms an output terminal on the anode side is insulated and fixed to a casing, and a metal plate for a cathode that forms a output terminal on the cathode side opposite to this metal plate for an anode. A metal plate material is insulated and fixed to a housing, a dielectric film is arranged between the metal plate material for the anode and the metal plate material for the cathode, and a dielectric film is further placed between the metal plate material for the anode and the metal plate for the cathode. A high-frequency noise reduction device characterized in that the metal plate material for an anode and the metal plate material for a cathode are integrated into an insulated state via a fixing means. (2) The anode metal plate forming the anode output terminal is insulated and fixed to the casing, and the cathode metal plate forming the cathode output terminal facing the anode metal plate is insulated to the casing. A ground plate connected to the ground side is placed between the metal plate for the anode and the metal plate for the cathode, and a dielectric film is placed between this ground plate and the metal plate for the anode and the metal plate for the cathode, respectively. Furthermore, the metal plate material for the anode, the metal plate material for the cathode, the ground plate, and the dielectric film are integrated into an integral structure via a fixing means while the metal plate material for the anode, the metal plate material for the cathode, and the ground plate are insulated.
