Abstract
A method of the invention manufactures a conductive resin composition having powdered silver and a reinforcing agent of the Mohs hardness 3.5 to 4.5 contained in binder resin, and forms an electrode substrate by use of the conductive resin composition. Thereby, hardness balance between phosphor copper and an electrode is regulated into the most appropriate state, and a wear resistance of both can be enhanced.
Claims4
An electrode substrate comprising:
- a substrate composed of polyethylene terephthalate;
- and
- an electrode composed of a conductive resin composition formed on the substrate,
- wherein the electrode slides on a sliding contact, and the conductive resin composition contains at least binder resin, powdered silver, and a reinforcing agent which is powdered nickel having a Mohs hardness of 3.5 to 4.5.
