Zusammenfassung:	The present invention provides a highly heat-resistant multilayer molded article having excellent adhesion between layers and which can be inexpensively produced and easily recycled. The multilayer molded article comprises an innermost layer containing a first polyarylene sulfide-derived resin composition comprising 95% to 80% by mass of a polyarylene sulfide-derived resin and 5% to 20% by mass of an olefinic (olefine-derived) elastomer, and an outer layer disposed on an outer-side of the innermost layer, comprising a second polyarylene sulfide-derived resin composition containing 5 to 35 parts by mass of reinforced fibers relative to 100 parts by mass of the first polyarylene sulfide resin composition.
