Abstract: 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.

Abstract: A method of manufacturing adhered components includes a process of applying adhesive to application areas on a surface of a first component, a process of placing a second component above the first component, and a process of pressurizing the second component toward the first component. In the pressurization process, the load applied to a pressurizer changes while sequentially undergoing a curvilinear increase period in which the load increases in a curved line as the compression amount of the adhesive increases, and a rapid increase period in which the load increases in a polygonal line with respect to the trajectory of the load in the curvilinear increase period as the compression amount increases. During pressurization by the pressurizer, the load is detected by a load sensor, the rapid increase period is detected based on the detection value of the load sensor, and the pressurization is stopped during the rapid increase period.
