PROBLEM TO BE SOLVED: To provide an adhesive composition capable of keeping adhesiveness for a long time, an adhesive sheet, a laminate, an image display device and an input-output device.SOLUTION: An adhesive composition contains (A) at least one block copolymer selected from an X-Y-X type hydrogenated styrenic block copolymer and an X-Y type hydrogenated styrenic block copolymer, (B) a softener which is a liquid at room temperature (23°C), (C) a terpenoid-based tackifier resin and (D) an aromatic tackifier resin, in the amounts of 10 pts.mass to 300 pts.mass inclusive of the (B) softener, 1 pts.mass to 30 pts.mass inclusive of the (C) terpenoid-based tackifier and 1 pts.mass to 50 pts.mass inclusive of the (D) aromatic tackifier respectively based on 100 pts.mass of the (A) block copolymer, and the content of the (C) terpenoid-based tackifier to the content of the (B) softener (content of the (C) terpenoid-based tackifier/content of the (B) softener) is 0.05 to 0.70 inclusive.SELECTED DRAWING: Figure 1 |
