Abstract

PURPOSE:To suppress generation of a radio noise in a distributor of spark-ignition type, by forming at least the end part of a rotor electrode with ferrite and forming a dielectric film to at least the end part in either side. CONSTITUTION:A rotor electrode 15 is formed with ferrite of a high resistance material in a high frequency range, and a silicon dielectric film 16 of silicon grease or the like is formed to the end part of said electrode. In this way, if the electrode 15 is formed with the ferrite, a capacitance discharge current is weakened by high resistance of the electrode itself, and intensity of the electric field by a generated radio wave can be effectively reduced. Further the dielectric film 16 of silicon grease or the like is coated to the point end part, then an electric charged particle generated during discharge is accumulated in the vicinity of said end part, and the intensified electric field is formed by the space charge to present an effective supply source of the charged particle at discharge, thus electric discharge voltage can be lowered.
