ABSTRACT:
A wet frictional plate including a made of a metal plate that is formed so as to have a plate thickness which changes to gradually increase from its outer circumferential portion toward its inner circumferential portion. Frictional materials are bonded to the surfaces of the metal plate while they are pressed and heated to make the frictional surfaces of the frictional materials parallel to each other. As a result, the density of the frictional materials increases in a direction from the outer circumferential portion of the wet frictional plate toward its inner circumferential portion.
