PROBLEM TO BE SOLVED: To prevent generation of a distortion in a panel body caused by a molding shrinkage of the second molded article in a method for molding a panel by injecting the second synthetic resin material on a part of a surface of the panel body composed of the first synthetic resin material in a mold to mold a frame-like part and integrate the frame-like part and the panel body into one body. SOLUTION: In the method for integrally molding the panel 4 by injection-molding the frame-like part 2 composed of the second synthetic resin material on the circumferential margin of the panel body 1 composed of the first synthetic resin material having a glass transition temperature Tg(°C), the frame-like part 2 is molded by injecting the second synthetic resin material with the surface temperature of the panel body 1 maintained not higher than (Tg-60°C).
