A frictional material is made of cloth which is impregnated with an impregnating agent such as a bituminous material, synthetic resin, etc. The cloth is woven by a multiple yarn made by twisting single yarns with reinforcing metal wires. The single yarn consists of a center core in the form of a roving or a yarn of inorganic fibers such as glass fiber, rock wool, ceramic fiber, etc. and a covering element in the form of a sliver of organic fibers such as staple fiber, aromatic polyamide fiber, flame-resistant fiber, etc. The frictional material obtained is excellent in physical strength and in resistance against heat, effective for preventing dispersion of dust and irritation to human bodies, and advantageous from the viewpoint of cost.
