Claim:
1. A resin composition, comprising: a substance reversibly reacting with a carbon dioxide gas; and a copolymer, comprising: a constitutional unit (1) expressed in a formula (1) below: where M represents cesium; and a constitutional unit (2) expressed in a formula (2) below: wherein a content of the constitutional unit (2) is from 1 mol % to 90 mol % with respect to a total content of the constitutional unit (1) and the constitutional unit (2), the substance reversibly reacting with the carbon dioxide gas is cesium carbonate or cesium hydrogencarbonate, and a content of the substance reversibly reacting with the carbon dioxide gas is within a range from 20 weight % to 90 weight % with respect to a total weight of the substance reversibly reacting with the carbon dioxide gas and the copolymer wherein the copolymer comprises a constitutional unit (3) selected from the group consisting of a constitutional unit derived from methacrylic acid alkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from maleic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, a constitutional unit derived from fumaric acid dialkyl ester having an alkyl group having a carbon number from 1 to 16, and a constitutional unit derived from itaconic acid dialkyl ester having an alkyl group having a carbon number from 1 to 16.
