Beschreibung
Zusammenfassung:	A manufacturing method for a molded article is provided, including: a preparing step of preparing an insert member having, on a surface, a first resin part containing a first thermoplastic resin; a filling step of inserting and fixing the first resin part of the insert member into a mold and filling a space between the first resin part and the mold with a molten second thermoplastic resin using an injection molding apparatus; and a pressure holding step of applying a holding pressure to the second thermoplastic resin that the space is filled with, wherein in the pressure holding step, a first holding pressure is applied until an inner temperature of the first resin part reaches a deflection temperature under load of the first thermoplastic resin, and a second holding pressure lower than the first holding pressure is applied after the inner temperature reaches the deflection temperature under load.
