(57) [Abstract] [Problem] High elasticity and non-adhesive or low-adhesion (tack-free) at around room temperature, yet exhibit excellent adhesiveness, thus achieving both adhesive workability and adhesiveness. Further, the present invention provides a pressure-sensitive adhesive composition having excellent durability and heat resistance. A storage elastic modulus [G ′] at room temperature is 2 × 10 6 dyne / cm 2 or more, adhesive strength at room temperature is 1 kg / 2 A pressure-sensitive adhesive composition having a width of 0 mm or more, in particular, a polymer having a polycarbonate structure as a base polymer is used to form the pressure-sensitive adhesive composition having the above storage elastic modulus [G '] and adhesive strength. . |
