PROBLEM TO BE SOLVED : To satisfy needs for compensating ultraviolet ray absorptive function by other constitutional members, for example an adhesive layer or the like as thinning of polarizing sheet protective film is proceeded with thinning image display device constitutional member and thereby sufficient ultraviolet ray absorptive function is hard to be provided. SOLUTION : There is provided a transparent double-sided adhesive sheet having a laminate structure having at least an intermediate layer (α layer) and a surface layer (β layer), which contain a (meth)acrylic copolymer (A) and a crosslinking agent (B), and the α layer contains a photopolymerization initiator (C) having light absorptive coefficient at wavelength of 405 nm of 10 mL/(g cm) or more and an ultraviolet absorber (D).
