PURPOSE: A manufacturing method for a disc of a multiple disc clutch is provided to simplify a manufacturing process and decrease waste of friction material by spreading liquid friction material to front and rear surfaces of an annular plate, pressing and drying surfaces. CONSTITUTION: A manufacturing method for a disc(28) of a multiple disc clutch includes a cutting process; a coating process and a pressurizing process. An annular plate(22) is cut from a steel roll plate, raw materials. Liquid friction material(24) is coated to front and rear surfaces of the annular plate in uniform thickness. Friction material of front and rear surfaces of the annular plate is pressed by upper and lower pressurizing frame and dried. Protrusion portions of the pressurizing frame make grooves(28a) for flowing oil to a surface of the friction material. Thereby, time for coating friction material is reduced.
