Abstract: The present invention provides a highly heat-resistant multi-layer molded article having excellent adhesion between layers and which can be inexpensively produced and easily recycled. The multi-layer molded article comprises an innermost layer including a first polyarylene sulfide-derived resin composition having 95% to 91% by mass of a polyarylene sulfide-derived resin and 5% to 9% by mass of an olefinic (olefine-derived) elastomer, and an outer layer disposed on an outer-side of the innermost layer, including a second polyarylene sulfide-derived resin composition having 5 to 35 parts by mass of reinforced fibers and 100 parts by mass of a third polyarylene sulfide-derived resin composition having 95% to 80% by mass of a polyarylene sulfide-derived resin and 5% to 20% by mass of an olefinic elastomer.
