Abstract
In a distributor for internal combustion engine, the rotor electrode is formed of a first electrode of a conductive metal, and a second electrode electrically connected to the first electrode. The second electrode is formed of the mixture of fine particles of resistive and conductive materials. The first electrode is made in contact with the center carbon of the distributor, and the second electrode is opposed to the stationary electrode of the distributor. The minimum length from the discharge end surface of the second electrode to the first connection between the first and second electrodes is selected to be 5 mm or above.
