An oxygen-absorbing composition of the present invention contains a gas-barrier resin as well as a salt of an unsaturated carboxylic acid and an oxygen absorption promoter that are dispersed in the gas-barrier resin. A cation that composes the salt of the unsaturated carboxylic acid is a cation of at least one element selected from the group consisting of alkali metals, alkaline earth metals, and aluminum. The oxygen absorption promoter is at least one selected from the group consisting of transition metal salts, radical generators, and photocatalyst particles. The unsaturated carboxylic acid has a molecular weight of 3000 or less.
