PROBLEM TO BE SOLVED: To provide a friction material for brakes ensuring stability, high-speed effects and fading characteristics equal to those of chopped strands of besalt fibers and maintaining the production cost at a low value while keeping abrasion characteristics. SOLUTION: The friction material is characterized by compounding powder of besalt as one of components of an inorganic filler in the friction material composed of a fiber base material, a friction regulator, a binder and the inorganic filler. The powder of the besalt is preferably compounded in an amount of 1-20 mass% based on the whole friction material composition and the average particle diameter of the powder of the besalt is preferably 1-150μm.
