Abstract: This adhesive contains an epoxy compound, a cationic catalyst, and an acrylic resin that includes acrylic acid and an acrylic acid ester having a hydroxyl group. The acrylic acid in the acrylic resin reacts with the epoxy compound, creating a link between the acrylic resin island part and the epoxy compound sea part, and strengthening the anchoring effect with respect to the epoxy compound sea part by roughening the surface of an oxide film. Furthermore, the hydroxyl-group-containing acrylic acid ester in the acrylic resin becomes electrostatically adhesive to wiring due to the polarity of the hydroxyl group. Excellent adhesive strength can be obtained by adhering, in this way, the entire cured product composed of the acrylic resin island part and the epoxy compound sea part to the oxide film.
