PROBLEM TO BE SOLVED: To improve production efficiency in manufacturing a friction plate. SOLUTION: A core plate 1 punched into a given shape in a core plate punching process 20 is surface-roughened, pretreated in a surface harshening process 30 and a cleaning process 40, coated with an adhesive agent both the sides in an adhesive agent coating process 50, overlapped with a friction material 2, punched into a given shape in a friction material punching process 60, in an overlapping process 70; thereafter, the overlapped work 3 is sent to a drying and hardening process 80. High-frequency heating is applied to the core plate 1 in contact with the adhesive agent to harden the adhesive agent, and the core plate 1 with the adhesive agent is heated and pressurized by a hot press 91 in a proper adhering process 90, thus completing the friction plate 4. Since the high-frequency heating is used in this case, the equipment can be small-sized, an amount of time required to manufacture the friction plate 4 is shortened, thus improving the production efficiency.
