PURPOSE: A ground metal device of a capacitor for microwave oven is provided to remove effectively the noise generated from a magnetron by absorbing or shielding unnecessary radio frequencies from the magnetron. CONSTITUTION: A ground metal device of a capacitor for microwave oven includes a rectangular ground plate(410), a plurality of insertion holes(430,440), and a plurality of extension tubes(450,460). The insertion holes are formed on both sides of an upper portion of the rectangular ground plate. The extension tubes are extended to each upper portion of the insertion holes. A projection portion(420) is formed on the rectangular ground plate. An RF absorption body is installed at an end portion of the extension tube in order to restrict the leakage of radio frequency.
