Abstract

The present invention provides a sterilized oxygen-absorbing resin composition obtained by performing at least: a sterilizing step of irradiating with radiation an oxygen-absorbing resin composition containing a transition metal catalyst and a thermoplastic resin (a) having a tetralin ring as a constituent unit; and a step of heating the oxygen-absorbing resin composition at a temperature equal to or higher than the glass transition temperature of the thermoplastic resin (a) and equal to or lower than 200° C., after the sterilizing step.
