PROBLEM TO BE SOLVED: To provide a method for producing a photocurable adhesive sheet by which the photocurable adhesive sheet having reduced difference in characteristics at both surfaces is produced by using an arbitrary photocurable adhesive composition by a simple apparatus at a low cost. SOLUTION: The method for producing the photocurable adhesive sheet having photocurable adhesive layers comprising the photocurable adhesive composition is characterized by the irradiation of the photocurable adhesive layers in an uncured state, formed by the coating of the photocurable adhesive composition with light from one surface side so as to be cured to 30-73% polymerization rate, and the additional irradiation of the adhesive sheet with the light from the other surface side to cure and to form the photocurable adhesive layers in a curd state. A photocurable double-sided adhesive sheet constituted of only the photocurable adhesive layers is suitable as the photocurable adhesive sheet. Each face of the photocurable adhesive layers is preferably protected by two separators. COPYRIGHT: (C)2006,JPO&NCIPI
