ABSTRACT:
A distributor having electrodes made of a sintered body composed of a composite material such that the distributor can suppress radio noises to thereby prevent electric interference. The material for the electrodes, the sintered body, is composed of 45-90 mol % of zinc oxide and 55-10 mol % of ferrite, which can suppress radio noises generated between the electrodes due to spark discharging. At the same time, the energy loss within such composite material is small and consumption of electrode can be restrained. Electrode durability is further improved by including bismuth oxide, manganese oxide and cobalt oxide in the electrode material. An ignition plug and electric discharge machine can also advantageously use the electrodes composed of such materials.
