PROBLEM TO BE SOLVED: To obtain a friction material which excels in frictional wear characteristics and productivity by including a friction regulator containing lamellar potassium octatitanate in a friction material. SOLUTION: This friction material is obtained by including a friction regulator containing lamellar potassium octatitanate in a friction material. The shape of the potassium octatitanate to be used with a major axis of 10-500μm and a minor axis (thickness) of 50-1000 nm is preferable. The content of the potassium octatitanate in the friction material is preferably 3-50 wt.%. The friction material comprises, for example, (A) 1-60 pts.wt. of base fibers (e.g. aramid fibers), (B) 20-80 pts.wt. of a friction regulator containing lamellar potassium octatitanate, (C) 10-40 pts.wt. of a binder (e.g. phenolic resin), and (D) 0-60 pts.wt. of other component(s).
