PROBLEM TO BE SOLVED: To provide a friction material capable of reducing noise occurrence, with good fading characteristics. SOLUTION: The friction material comprises fiber base material, friction adjusting material, binder, and inorganic filler. It contains the powder of calcium carbonate which is acquired by mechanically crushing a raised/weathered hermatype as one component of the inorganic filler. The powder of calcium carbonate is preferred to be contained in the friction material by 5-65 wt.%. COPYRIGHT: (C)2003,JPO
