Abstract
A slurry of suspended formation fiber and binder fiber is brought to pass through a suction unit to form a molded member. Longitudinally extending channel portions are formed on both inner and outer peripheral surfaces of the molded member, and a wall portion is formed to close one end of the channel portions of the inner peripheral surface. Further, opposite surfaces of the channel portion at the other end of the molded member are closed by pressing from outside and bonded by binder resin which is impregnated into the molded member.
