Abstract:
A carbonaceous material is produced by mixing a carbon powder and a binder. A metal powder is mixed into the thus-produced carbonaceous material in an amount of from 10% by weight to 60% by weight (inclusive) relative to the weight of the carbonaceous material. The thus-mixed carbonaceous material and metal powder is pressed and molded. A brush base is produced by firing the pressed and molded carbonaceous material and metal powder. The thus-produced brush base is impregnated with an oil. The impregnation ratio of the oil may be, for example, 0.5% by weight or more relative to the weight of the mixed carbonaceous material and metal powder.
