Abstract
In a method of producing a wet friction material according to the present invention, a water soluble material is dispersed into a raw paper including a fibrous base material, a filler, and a friction adjusting agent. Then, the raw paper is passed through water to dissolve the water soluble material to provide porosity. Thereafter, the raw paper is immersed with thermosetting resin, and heated and hardened to thereby produce a wet friction material.
