The purpose of the present invention is to provide an adsorbent composition which can be easily formed into a film by inflation molding at relatively low temperatures even if zeolite is contained therein, and which is not susceptible to the formation of a pin hole. An adsorbent composition which is a resin composition containing a resin, zeolite and a metal soap, and wherein the metal soap contains a long-chain fatty acid calcium, which is a divalent salt of calcium and a long-chain fatty acid having 5-30 carbon atoms, and a long-chain fatty acid zinc, which is a divalent salt of zinc and a long-chain fatty acid having 5-30 carbon atoms.
