Abstract
A friction member has an improved anticorrosiveness and an improved shearing strength. For this purpose, the friction member includes a cured organic film (2) formed on a surface of a backing plate (1) and sandwiched between an adhesive layer (3) on a friction material (4) and the backing plate. The film (2) has a thickness sufficient to protect the backing plate (1) against corrosion. The organic film (2) is not affected by heat and/or pressure during the bond forming molding of the backing plate (1) and the friction material (4), so that the anticorrosiveness and the shearing strength of the friction member is improved.
