Abstract
An adhesive composition contains a modified polyolefin resin. The polyolefin resin is obtained by modifying a polyolefin resin with an unsaturated carboxylic acid and a radically reactive aromatic compound. The polyolefin resin has a heat of fusion of 10 J/g or less, which is measured in conformity with JIS K7122. A modified content of the unsaturated carboxylic acid content with respect to the modified polyolefin resin is more than 0.5% by mass and less than 5% by mass. A modified content of the radically reactive aromatic compound with respect to the modified polyolefin resin is 0.1% by mass or more and less than 3% by mass.
