摘要： PURPOSE:To be able to suppress radio wave noise permanently by applying shot brust to at least the discharge part of a negative electrode side out of a rotor electrode and a side electrode to devastate the surface above roughness 20Z equally in the case of a distributor for an internal-combustion engine. CONSTITUTION:A rotor electrode 1 made of brass, stainless or the like before fixed to a rotor base body 2 is set to a jig 3 which can fix a large number of electrodes heapingly with only a discharge surface 1a exposed. And roughness of the surface concerning the discharge surface 1a of the electrode 1 is controlled to be between 20-40Z by spraying a grind-and-sweep material of burnt alumina or the like with a grain size of around 30 mesh by a shot gun 4. Discharge starting voltage between the rotor electrode and a side electrode can be consequently reduced to 1/2 of the traditional, and noise current mutually related to the discharge starting subsequently declines. Also, effect can last for a long term owing to the simple structure.
