PROBLEM TO BE SOLVED: To improve power transmission characteristics in a high temperature region, besides achieving weight reduction, while attaining high transmission power in a high temperature region and a high rotation region of a friction clutch by using a carbon/black lead material like CC composites. SOLUTION: In the friction clutch, a friction disk assembly comprises a center hub section and a friction disk. While the friction disk includes a first friction surface and second friction surface, a flywheel opposing to the first friction surface includes a third friction surface, and a pressure plate opposing to the second friction surface includes a fourth friction surface. At least one or more in these friction surfaces from first through fourth is formed of a dissimilar material combining the carbon/black lead material with a metal/ceramic material, and has a configuration in which the carbon/black lead material forms a carbon/black lead material based friction surface and the metal/ceramic material forms a metal/ceramic material based friction surface.
