Abstract

An anisotropic conductive adhesive contains conductive particles dispersed in a resin composition, wherein the resin composition includes a radical polymerization resin (A), an organic peroxide (B), a thermoplastic elastomer (C) and a phosphoric ester (D). The resin composition can further contain an epoxy silane coupling agent (E) represented by formula (2) or (3). The resin composition is mixed with other components after the radical polymerization resin (A), the thermoplastic elastomer (C), the phosphoric ester (D) and the epoxy silane coupling agent (E) are reacted. It is also possible to preliminarily react only the phosphoric ester (D) and the epoxy silane coupling agent (E) and to react the product of the preliminary reaction with the radical polymerization resin (A) and the thermoplastic elastomer (C), and then to add other components. The anisotropic conductive adhesive of the present invention can be used for electrical joining of electronic or electric parts of electrical apparatus.
