There are disclosed a friction material composition which comprises a fibrous material except for asbestos, an inorganic friction regulator, an organic friction regulator and a binder, part of the inorganic friction regulator is &#x3b1; alumina and &#x3b3; alumina in combination, a weight ratio of the &#x3b1; alumina and the &#x3b3; alumina, &#x3b1; alumina:&#x3b3; alumina, is in the range of 1:20 to 1:5, and part or whole part of the binder is a silicon-containing phenol resin, and a friction material obtained by molding the friction material composition under heating and pressure.

A brake lining of a vehicular brake device is produced by a friction material which has a characteristic that a friction coefficient of the friction material decreases according to an increase of a sliding speed between the brake lining and a rotational member when the sliding speed is greater than or equal to a predetermined speed during the braking operation, and the friction coefficient is substantially constant when the sliding speed is smaller than the predetermined speed.
