A friction material is provided with a baked carbonized organic material as the binder thereof. The friction material has a degree of compression deformation at room temperature of from 0.3 to 2.5% under a load of 4 MPa and from 1.0 to 4.5% under a load of 10 MPa. The compression deformation ratio of the degree of compression deformation at 300° C. to the degree of compression deformation at room temperature is from 1.0 to 1.5 under a load of from 1 to 10 MPa. The baking carbonization step comprises carbonizing an organic material in any atmosphere of vacuum, reducing gas or inert gas at a temperature of from 550° C. to 1300° C. with applying a load thereto.
