发明名称 ADHESIVE SHEET AND PEELING METHOD
摘要 PROBLEM TO BE SOLVED: To provide: an adhesive sheet that can be closely adhered to an adherend, and is excellent in peelability after adhering; and a peeling method of the adhesive sheet.SOLUTION: An adhesive layer is laminated to at least one surface of a core material film including a polymer in which a storage modulus at 25°C is 500-5,000 MPa, and a storage modulus at 50°C is 1-200 MPa to obtain an adhesive sheet. In at least one end of the adhesive sheet, an end face of the core material film extends than an end face of the adhesive layer. Moreover, when the adhesive sheet is adhered to an adherend, adhesive strength of the adherend and the adhesive layer may be smaller than the adhesive strength of the adhesive layer and the core material film.
