Abstract
An ignition distributor having a radio wave noise suppressing function has a rotor electrode and counter electrodes. At least the cathodic one of the rotor electrode and the counter electrodes is provided at its end with a coating layer of a material which is a mixture of a metal oxide having a high electric resistance and a metal oxide which constitutes a dielectric body stable in a high-temperature atmosphere. The metal oxide having high electric resistance consists essentially of 10 to 50 wt % of Cu.sub.2 O and 90 to 50 wt % of CuO, while the metal oxide constituting the dielectric body essentially consists of 70 to 90 wt % of alumina with respect to the weight of the metal oxide having high electric resistance.
