Abstract
Abstract A capacitor network mounted to an input-output unit of a computer for eliminating noises, which disposes on one surface of a dielectric substrate a plurality of electrodes and on the other surface of the same at least one common electrode opposite to the plurality of electrodes so that lead terminals connected to each of the plurality of electrodes and earth terminals connected to the common electrode are formed of metal strip. A pair of terminal blocks formed of the metal strip are inserted onto the dielectric substrate from both lateral sides thereof so as to hold the dielectric substrate between the lead terminals and the earth terminals, each terminal being fixed to the respective electrode, and thereafter the metal strip is cut off, thereby forming a three-terminal capacitor leading out the terminal from each electrode. Since the lead terminals and earth terminals are connected to the metal strip, parts, such as the terminals, are easy to manufacture and assemble and areas of the electrodes and common electrode can be made larger, thereby obtaining effective electrostatic capacity.
