A method of manufacturing a friction material is provided to keep the quality of the friction material and cut down the molding process time without using any special molding frame. A method of manufacturing a friction material(4) contains a step of pressing and heating the molding material which is a raw material of the friction material in the molding frame. The mold temperature of the molding process is 190~230 degrees, and the pressure is 100~200Mpa. The molding material which is the raw material of the friction material is pressed and heated in the molding frame having upper, center, and lower dies(1,2,3). The center die is formed with a porous material, and the molding material is an assembly. The molding material is pre-heated.
