ABSTRACT:
A distributor for an internal combustion engine which exhibits a high suppressing effect of noise radio waves even by measurement in accordance with quasi-peak detection and assures stabilized discharge in a discharge gap. The distributor comprises a rotor electrode provided on a distributor rotor secured to a rotary shaft which is connected to be rotated in a synchronized relationship by rotation of a crankshaft of the engine. A plurality of side electrodes are disposed along a locus of rotation of the distributor rotor electrode with a discharge gap left therebetween. A dielectric layer of aluminum oxide or silicon carbide is formed at a location of one or each of a pair of opposite faces of the distributor rotor electrode adjacent and end opposing to the side electrode. A method of producing such distributor rotor electrode with a dielectric layer is also disclosed.
