PURPOSE:A mixture of a powder of magnetic material with a resin as a binder is subjected to compression molding under application of magnetic field to produce a friction material with high friction coefficient, high tensile strength and high abrasion resistance. CONSTITUTION:A powder of magnetic material or a mixture thereof with other substances is thoroughly kneaded with a resin as a binder such as a melamine resin and subjected to compression molding under application of magnetic field (static or variable magnetic field of 1,000-5,000G), solidified by cooling to give the objective friction material.
