PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing metal mold of a frictional material for dispensing with a large-scale press device, by reducing generation of polishing powder, by shortening grinding work, while reducing a brake squeak. SOLUTION: This device has a process of manufacturing a spare mold 30 having inclined faces 30b and 30b by pressurizing and hardening a powdery raw material without heating in a preliminary molding metal mold 10, and a process of forming the spare mold into the frictional material 3 having inclined faces 3b and 3b of a desired angle in a position of the inclined faces 30b by heating and pressurizing the spare mold in a molding metal mold 20; and is characterized by setting an angleαof the inclined face of the spare mold 30 larger than an angleβof the inclined face of the frictional material 3.
