PROBLEM TO BE SOLVED: To provide a friction material containing a glass fiber, produced through a step for polishing a friction surface, and hardly causing rust in a mating material when water or the like invades into the space between the friction material and the mating material. SOLUTION: The friction material having the friction surface prepared by polishing the surface of a molded article prepared by molding the composition containing a rubber of a main material and the glass fiber by heating and pressurizing allows the glass fiber to be exposed nearly homogeneously to the friction surface by nearly homogeneously dispersing the glass fiber in the composition by using the easily dispersible glass fiber and molding the dispersed product.
