Abstract
The adhesive composition according to the invention of the present application contains a block copolymer (a) having a block mainly comprising a vinyl aromatic monomer unit, a tackifier (b) and an oil (c), in which the block copolymer (a) contains a partially hydrogenated block copolymer (a-1), the partially hydrogenated block copolymer (a-1) has a vinyl aromatic monomer unit and a conjugated diene monomer unit, the content of the vinyl aromatic monomer unit is 10 mass % or more and 19 mass % or less based on 100 mass % of the partially hydrogenated block copolymer (a-1), and the hydrogenation ratio of double bonds contained in the conjugated diene monomer unit in the partially hydrogenated block copolymer (a-1) is 15 mol % or more and less than 80 mol % based on the total (amount) of double bonds before hydrogenation.
