Abstract: A method of manufacturing a flow sheet capable of smoothening the surface of the flow sheet for a paper machine and easily handling the flow sheet, wherein reinforcement fibers are disposed in a mold (5), and the entire part of the mold (5) is covered by sealing members (10) and (11) to form a closed space (12) in the sealing members (10) and (11). While air in the closed space (12) is sucked from one end of the closed space (12), a matrix resin is supplied from the other end of the closed space (12) to the reinforcement fibers, impregnated into the reinforcement fibers, and hardened. As a result, the flow sheet having a surface smoothness of 0.25 μm or less in arithmetic average roughness can be provided.
