    摘要: Provided is an adhesive composition that does not contain a solvent and that is excellent in productivity and self-adhesiveness. The object is attained by an adhesive composition containing an olefin-based polymer, in the adhesive composition, no inorganic particles being blended, and the adhesive composition having a storage modulus at 20° C. of 0 to 1.0×107 Pa, and a storage modulus at 40° C. of 5.3×105 Pa to 1.0×109 Pa.
