CIRCUIT CONNECTING MATERIAL AND CONNECTION STRUCTURE OF CIRCUIT MEMBER

摘要

A circuit-connecting material, and a connection structure of a circuit member are provided to prevent the shortage due to the agglomeration of conductive particles and to improve connection reliability. A circuit-connecting material(1) of two layers which is interposed between the circuit electrodes(2,6) facing each other and connects electrically the electrodes of the pressurization direction by pressurizing the circuit electrodes facing each other. The circuit-connecting material has a laminated structure comprising an anisotropic conductive adhesive layer where a conductive particle is dispersed, and an insulating adhesive layer, wherein the average diameter a of the conductive particle and the thickness b of the anisotropic conductive adhesive layer satisfy the relation of the mathematical equation represented by a>=b.
