PROBLEM TO BE SOLVED: To provide a molding produced by gas injection molding using an aromatic polycarbonate resin composition, having excellent heat resistance, mechanical characteristics, surfaces properties, impact resistance and coating properties and being usable in a wide range of environments at low to high temperatures. SOLUTION: A manufacturing method comprises manufacturing a molding having a hollow part by gas injection molding, using a thermoplastic resin composition (C) containing an aromatic polycarbonate resin (A1) and a polyester resin (A2) in an (A1)/(A2) mass ratio of (55-99)/(45-1) and talc or wollastonite (B) having an average particle size of 0.5-5.0μm, measured by a laser diffraction type particle size distribution measuring apparatus, and containing practically no particles of particle sizes of≥15μm, in a mass ratio of 1-60 pts.mass relative to the combined amount of (A1) and (A2) of 100 pts.mass.
