Zusammenfassung:It is intended to suppress a phenomenon of clutch squeaking in an initial stage of usage. The present clutch friction material (10) includes a base material (20), an intermediate layer (30) and an outermost surface layer (40). The base material (20) contains a rubber material and a thermosetting resin. The intermediate layer (30) is disposed on the base material (20) and includes either a glassy carbon structure or a graphite structure formed as a result of thermal curing of the thermosetting resin contained in the base material (20). The outermost surface layer (40) is disposed on the intermediate layer (30) and contains a payrolysate produced as a result of pyrolysis of rubber and resin components contained in the base material (20).
