Abstract: The present invention addresses the problem of providing a friction material for a disc brake pad, which is able to secure effective braking performance and wear resistance during the high speed and high load braking while satisfying laws and regulations relating to copper content. The solution to this problem is using a non-asbestos organic (NAO) friction material for a disc brake pad, which is formed by molding a friction material composition comprising a fiber base material, a binder, and a friction modifier, and specially comprising, as an inorganic friction modifier, 1-10 weight % of one or any combination of two or more of aluminum particles, aluminum fibers, alloy particles mainly containing aluminum, and alloy fibers mainly containing aluminum relative to the total amount of the friction material composition, 5-20 weight % of hard inorganic particles with an average particle diameter of 1-20 ?m and a Mohs hardness of 4.5 to 8.0, and copper content of less than 0.5 weight %.
