Abstract
In a wet friction material, inorganic filler of small particle size is added to fill clearances or space between fibers with the inorganic filler. The inorganic filler is attached to the fibers with each other to reinforce strength of the wet friction material when an impregnated resin is hardened. Absolute specific gravity of the inorganic filler is set at a fixed value so as to make its compounding quantity small, thereby assuring a pore diameter of a friction material substrate without filling pores of the friction material substrate with the inorganic filler.
