Provided is an adhesive sheet for temporary fixing use, which cannot come off or cannot be detached even when an electronic material on a thin film is fixed temporarily onto a hard substrate using the adhesive tape and then the resultant product is subjected to an etching treatment or the like in an electronic component production process. An adhesive sheet for temporarily fixing an electronic component, which comprises a base material and an adhesive agent layer formed from a cured product of an adhesive agent composition and provided on both surfaces or one surface of the base material, said adhesive sheet being characterized in that the adhesive agent composition comprises at least a component (A) that is a silyl-terminal polymer, a component (B) that is a silane coupling agent and a component (C) that is a curing catalyst, the component (A), i.e., the silyl-terminal polymer, has a specific structure, and a component (D) that is an adhesiveness-imparting resin may be additionally contained or may not be contained in the adhesive agent composition wherein the amount of the component (D), i.e., the adhesiveness-imparting resin, is less than 10 parts by weight relative to 100 parts by weight of the component (A), i.e., the silyl-terminal polymer, when the component (D) is contained. |
