A friction material exhibiting a great coefficient of friction, as compared to that of the conventional friction material, which is produced with the use of an organic paper-like substrate. The friction material is composed of the paper-like substrate of a fibrous material, and an inorganic binder with which said substrate is impregnated. When friction is produced, the inorganic binder exhibits friction characteristics so that a great coefficient of friction can be effected, as compared to the cases organic binders such as phenol resin are used.
