Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a favorable resin composition, by which an aromatic polyester resin as a main source material is efficiently heated and melted without causing discoloration or degradation in performances of the resin mixture. SOLUTION: The method for manufacturing a resin composition comprises using an extruder 1 having a main source material feeding port 4 and a side feed 7 and feeding a resin (A) as a main source material and a second resin component (B) having a melting temperature lower than that of the resin (A) into the extruder to mix, wherein after the second resin component (B) is fed through the main source material feeding port 4, the resin (A) is fed through the side feed 7 to be mixed.
