摘要：
A carbonaceous material is fabricated by a mixture of carbon powder and a binder. 10 % by weight or more and 60 % by weight or less of metal powder to the fabricated carbonaceous material is mixed. The mixed carbonaceous material and metal powder are pressurized and formed. A brush base material is fabricated by burning of the pressurized and formed carbonaceous material and metal powder. The fabricated brush base material is impregnated with oil. An impregnation rate of the oil to the mixed carbonaceous material and metal powder may be 0.5 % by weight or more, for example.
