Adhesive sheet
An improved adhesive sheet can exhibit an excellent anti-blister characteristic without susceptible to the property of the base material. The adhesive sheet includes a base material that is formed from a base material film and a thin film laminated onto the base material film, an adhesive layer and a release sheet. The adhesive layer contains an adhesive component and a curing component as its main composition. The curing component is of the type that is to be cured by irradiation with radiation. As for such radiation-curing type component, materials containing acrylic-based monomer or oligomer can be used. The adhesive layer has a storage modulus (dynamic modulus) in which a ratio of storage modulus G2&#8242;/G1&#8242; of the adhesive layer lies within the range of 1.2 to 50, wherein G1&#8242; is a storage modulus of the adhesive layer before curing at a temperature of 25&deg; C. and at a frequency of 1 Hz, and G2&#8242; is a storage modulus of the adhesive layer after curing at a temperature of 25&deg; C. and at a frequency of 1 Hz.
