Zusammenfassung:	PURPOSE:To prevent cracks and breakages from occurring on a molded resin- made functional part or a runner part connecting it even in a high temp. or low temp. atmosphere by performing, outsert molding of a functional part on a base sheet with a cut or a perforated hole by using a polyacetal copolymer resin with a crystallization time of at least a specified time. CONSTITUTION:As a resin used for outsert molding, a polyacetal copolymer resin with a crystallization time of at least 5min. is used. This copolymer resin is pref. a polymer wherein 3-30wt.% oxyalkylene unit with the carbon number of at least 2 are incorporated in a polymer wherein oxymethylene unit is a main constitutional unit and the melt index is pref. 1.0-60g/10min.
