<P>PROBLEM TO BE SOLVED: To provide a friction material, in which the strength deterioration or the wear characteristic deterioration of the friction material does not occur even if heat treatment is applied, such treatment is allowed at low energy, and stability of effectiveness of a brake, a high-speed effect and a fade characteristic can be secured; and to provide a method for manufacturing the friction material. Ž<P>SOLUTION: The friction material is prepared by forming a surface layer containing a flammable material burnt at 230°C or higher on a base material layer containing a fiber substrate, a binding material, and a friction adjustment material and heat treatment.
