PROBLEM TO BE SOLVED: To provide a friction material composition that has a constitution of low environmental hazard with the copper content not exceeding 0.5 mass%, and that yields a friction material effective for automobile fuel consumption improvement by having a good effectiveness characteristic, wear resistance and BTV characteristic, and furthermore by being light-weight; and also to provide a friction material and member using said friction material composition. ! SOLUTION: Provided is a friction material composition containing a binder, an organic filler, an inorganic filler and a fiber base material, and in which the content of copper as an element does not exceed 0.5 mass%, and in which a ferrous fiber or ferrous powder is contained by 1 to 3 mass% as well as wollastonite is contained by 10 to 30 mass% as the fiber base material. !
