摘要： A method for producing a multilayer molded article that includes a resin body and a skin material on a surface of the resin body, which method uses a mold having male and female molds. The shortest horizontal distance of a mating gap between the horizontally outermost wall surface of the male mold to which the skin material contacts and the horizontally innermost wall surface of the female mold to which the skin material contacts is 0.25 to 3 times the minimum thickness from which the once compressed skin material can restore the original thickness. The shortest length L in a mold closing direction of a mated part formed between the outermost wall of the male mold to which the resin melt contacts and the innermost wall of of a flange of the female mold satisfies the equation:(t.sub.1 -t.sub.0 +10)mm.gtoreq.L.gtoreq.(t.sub.0 -t.sub.0)mmwherein t.sub.1 is a distance (mm) between the male and female molds when the resin melt first reaches the horizontally outermost edge of the male mold, and t.sub.0 is a distance (mm) in the mold closing direction between the same points on the male and female molds as those used for measuring t.sub.1 when the mold closing is completed. In this method, squeeze-out of a resin melt during molding is prevented, and a multilayer molded article having no blanching, breakage or wrinkle of a skin material is produced.
