Abstract:
An adhesive sheet, comprising:a base material; and an adhesive layer which contains, as its main component, an adhesive component and a curing component, wherein the adhesive layer has as its main composition a component selected from the group consisting of alkyl esters of acrylic acid, alkyl esters of methacrylic acid, and mixtures thereof and wherein the adhesive layer has a storage modulus (dynamic modulus) in which a ratio of storage modulus G2â€²/G1â€² of the adhesive layer lies within the range of 1.2 to 50, wherein G1â€² is a storage modulus of the adhesive layer before curing at a temperature of 25Â° C. and at a frequency of 1 Hz, and G2â€² is a storage modulus of the adhesive layer after curing at a temperature of 25Â° C. and at a frequency of 1 Hz.
