PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition that achieves a pressure-sensitive adhesive sheet having high resistance to a continuous stress.SOLUTION: A pressure-sensitive adhesive composition includes a base polymer composed of a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound and a tackifier resin having a hydroxy value of ≥80 mgKOH/g. A pressure-sensitive adhesive sheet having high resistance to a continuous stress can be achieved by the pressure-sensitive adhesive composition. |
