ABSTRACT:
An ignition distributor for an internal combustion engine with reduced electric discharge energy and suppressed radio noise generation comprises a rotor electrode capable of rotary motion and a plurality of stationary electrodes arranged substantially in a circle around the rotor electrode through an electric discharge clearance therebetween, where the rotor electrode is made of a sintered mixture comprising zirconium oxide and an electroconductive inorganic compound having a specific resistance of not more than 10.sup.6 .OMEGA.cm as main components. The sintered mixture can be ZrO.sub.2 and an oxide selected from ZnO, NiO and CoO; or ZrO.sub.2, aluminum oxide and an oxide selected from ZnO, CoO, Al.sub.2 TiO.sub.5 and SrTiO.sub.3 or a carbide selected from ZrC, TiC and TaC.
