| abstract | PROBLEM TO BE SOLVED: To provide an adhesive sheet which exhibits excellent step followability even in a high-temperature environment or an ultraviolet irradiation environment and has excellent durability. The present invention is a pressure-sensitive adhesive sheet having a photocrosslinking property, wherein the pressure-sensitive adhesive sheet has a glass transition temperature (Tg) of −50 ° C. to −40 ° C. and a weight average molecular weight of 330,000 to 400,000. It contains a (meth) acrylic copolymer, has a tensile stress of 0.3 N / mm 2 or less at a tensile elongation of 2000% before photocrosslinking, and has a tensile elasticity of 50 kPa or more and 300 kPa or less before photocrosslinking. When the tensile elasticity before cross-linking is a and the tensile elasticity after photo-crosslinking is b, b / a is less than 3.0, and a high-pressure mercury lamp with an illuminance of 80 mW / cm 2 is used, and the integrated light amount is 2000 mJ. The present invention relates to an adhesive sheet in which the gel content of the photocrosslinked adhesive sheet after photocrosslinking by irradiating ultraviolet rays so as to be / cm 2 becomes 20% or less.
