An adhesive, and adhesive-fixed body, an electronic apparatus and a watch

摘要

The present invention uses an adhesive having high water resistance to realize an adhesive-fixed structure having excellent waterproofness and causing less changes in properties of an adhesive layer with time. An adhesive-fixed body of the present invention is obtained by bonding and fixing a body and a cover glass as exterior parts of a watch with an adhesive layer. The adhesive which constitutes the adhesive layer is a curable adhesive containing: 100 parts by weight of prepolymer resin having polytetramethylene oxide as a main chain and methacryl groups or acryl groups at both ends of the main chain or in side chains; 50 to 300 parts by weight of at least one selected from acrylic monomers or methacrylic monomers containing isobornyl acrylate, isobornyl methacrylate or a mixture thereof; and a silane coupling agent.
