PROBLEM TO BE SOLVED: To provide a method for manufacturing a transition metal compound- containing polyamide (polyamide resin composition) of high qualities having excellent oxygen-absorbing performances with high productivity while suppressing gelation in a polymerization step. SOLUTION: The method for continuously manufacturing a polyamide resin composition comprises a continuous manufacturing process comprising a step for preparing a raw material, an amidation step, an initial polymerization step and a latter polymerization step, where the supply accuracy C/A (in a molar ratio) of a dicarboxylic acid (C) and a diamine (A) from the step for preparing a raw material to the amidation step is 0.975-1.025 and introduction of a transition metal compound into the polyamide resin and adjustment by an acid anhydride of the composition ratio CEG/AEG of a carboxylic end group (CEG) to an amino end group (AEG) are carried out in the latter polymerization step.
