The present invention relates to a method of manufacturing a FRP claim jipjinpan excellent in the surface smoothness is high dust-collecting performance. According to the invention, the smooth substrate 10 onto the coating a resin having a carbon powder mixed laying a conductive carbon mat (5), and laminating a glass fiber mat (6) on it, as needed, and coated with a resin first forming a surface layer (1), and laying a further conductive carbon mat (7) onto a smooth substrate (10) coated with a resin having a carbon powder mixed and laminating a glass fiber mat (8) on it, as needed the method comprising the steps of: applying a resin to form a second surface layer (2), placed in a glass fiber mat (9) in the upper surface of the first surface layer (1) coated with a resin forming the adhesive intermediate layer (3), the the step of bonding the intermediate layer (3) is facing the second surface layer (2) before it is cured to the substrate 10 side is placed on the adhesive intermediate layer (3) such that the surface compression, curing the pressed plate member the method of manufacturing a FRP electric jipjinpan is provided, characterized in that consisting of.
