Beschreibung
Zusammenfassung:	A friction material composition that does not contain copper, which has a high environmental load, or containing copper in such small amount as to be not more than 0.5 mass % and that enables decrease in brake vibration in braking at high temperatures when used in a friction material such that for an automobile disc brake pad, is provided. A friction material obtained by molding the friction material composition is also provided. The friction material composition contains a binder, an organic filler, an inorganic filler, and a fibrous base material, and the friction material composition contains no copper as an element or contains not more than 0.5 mass % of copper, and also contains 2 to 5 mass % of steel fibers that have fiber lengths of 2500 µm or less.
