The present invention relates to resin pellets which comprises a thermoplastic resin (A) and an oxidation catalyst (B) which is not supported by any carrier, wherein if the peak area in the vicinity of 1715 cm−1 is defined to be Ic and the peak area observed in the vicinity of 1470 cm−1 is defined to be Im in the IR spectroscopic measurement of the pellets, the ratio: Ic/Im observed for the surface of the pellet is greater than that observed for the interior thereof. The pellets are thermoplastic resin pellets excellent in the oxygen-absorbing capacity and accordingly, they can suitably used as pellets for molding an oxygen absorptive resin article.
