A friction material contains a friction adjuster, a binder and an inorganic filler. The friction material further contains randomly shaped rubber chips which contain machining dust derived from friction material, and rubber binding the machining dust. The rubber chips are preferably sized so as to pass through a 16-mesh sieve. Since the friction material contains machining dust of friction materials, it is possible to reduce wastes and the cost of the friction material. Still, the friction material shows sufficient basic properties comparable to conventional friction materials, including environmental friendliness, braking effect, and reduced squeal and other noise.
