摘要： A laminated structure is manufactured using an extruder die in which an ejection port is provided, the laminated structure including a core layer, a first surface layer, and a second surface layer. The extruder die includes a first surface layer material conveyance path through which a raw material of the first surface layer is conveyed, a second surface layer material conveyance path through which a raw material of the second surface layer is conveyed, and a core layer material conveyance path through which a raw material of the core layer is conveyed. The paths merge at the ejection port. The extruder die has a shape in which a downstream portion downstream of a merging location that is the ejection port does not contact the injected laminated structure formed of the raw materials. The laminated structure is injected by causing viscous fluids as the raw materials into the paths, respectively.
