To provide a molding method of panel components which can improve the quality of molded parts.
In a bending process, a panel material 20 is bent to form a linear top part 20A so as to move closer to a curviform molding shape as a whole. In an outrigger molding process after the bending process, while restraining the peripheral edge part 20B of the panel material 20 over all the circumferences, outrigger molding is carried out to molding shape by making a direction along the direction facing to the top part 20 as a press direction (the direction of arrow B). Here, the panel parts which are molded product after molding serve as a shape in which is attitude maintainable on a plane by making three points in the peripheral edge parts as a support point. Moreover the bending direction (the direction of arrow A) to the panel material 20 in the bending process and the press direction (the direction of arrow B) to the panel material 20 in the outrigger molding process are set up to coincide with the direction perpendicular to an imaginary plane which contains all of the support points in the molded product condition after molding.
