ABSTRACT:
A disc type composite part for use in electrical and electronic equipment which includes a disc substrate of ceramic dielectric material having a through-opening formed at its central portion, a first electrode and a second electrode respectively provided adjacent to the outer periphery and around the through-opening on one surface of the substrate, a third electrode provided on the other surface of the substrate, a shortcircuiting member for selectively shortcircuiting the third electrode with the first or second electrode, resistor elements connected for bridging between the first and second electrodes so as to extend over the one surface of the substrate without following the diametrical direction of the substrate, and an electrically insulating covering layer formed at least on the one surface of the substrate.
