An oxygen-absorbing composition for a low-humidity environment includes a reduced metal and an accelerator having at least one of iodide and bromide. The accelerator may have at least one of a metallic iodide salt and a metallic bromide salt. The reduced metal and the accelerator may be included in a dry state and the oxygen-absorbing composition may take the form of particles. The oxygen-absorbing composition may be a resin composition made by kneading an oxygen absorber with a thermoplastic resin.
