An adsorbent composition that is a resin composition containing a polyolefin resin, zeolite, and a metallic soap, wherein the metallic soap contains a calcium salt of a long-chain fatty acid that is a divalent salt of a fatty acid long-chain fatty acid having 5 to 30 carbon and calcium atoms, and a zinc salt of a long-chain fatty acid which is a divalent salt of a long-chain fatty acid having 5 to 30 carbon and zinc atoms , in which the molar ratio of the calcium salt of a long chain fatty acid to the zinc salt of a long chain fatty acid is 1.4 to 2.8, and in which the metallic soap is contained in 1.4% by weight to 3.4% by weight with respect to the polyolefin resin, in which the zeolite is contained in 30% by weight or more with respect to the entire composition, and in which the salt of a long-chain fatty acid and the zinc salt of a long-chain fatty acid are calcium stearate and stearate. or zinc, respectively. |
