<P>PROBLEM TO BE SOLVED: To provide a multilayer molded article formed of three or more layers and having an outer peripheral end part formed of two layers, the outer peripheral end part having a required minimum thickness, thereby exhibiting a good shape and characteristics. <P>SOLUTION: This multilayer molded article 1 is molded by transferring an intermediate molded article molded, as a first layer, with a minimum-volume mold cavity 12a, among a plurality of mold cavities having different volumes, to a larger-volume mold cavity. A second layer is lamination-molded, and thereafter, the intermediate molded article is sequentially transferred to each mold cavity up to the N-th layer for lamination molding. The multilayer molded article 1 with three or more layers (N layers) thus obtained includes a collar part 6 with two layers formed on the whole periphery of the multilayer molded article. Besides, the main part 75 which is a part other than the collar part 6 of the multilayer molded article is formed of the N layers. <P>COPYRIGHT: (C)2013,JPO&INPIT |
