ADHESIVE COMPOSITION, CIRCUIT CONNECTION MATERIAL AND CONNECTION STRUCTURE, AND CONNECTION METHOD FOR CIRCUIT MEMBER

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition attaining secure insulation between neighboring connecting terminals, when circuit members having a minute connecting terminal are mutually connected, and a circuit connection material using the composition. SOLUTION: This adhesive composition 50 comprises an adhesive component 20 and electroconductive particles 10A dispersed in the adhesive component 20, wherein the conductive particle 10A comprises a nuclear particle 1 having conductivity and an insulating coating containing an organic polymer compound and being placed on the surface of the nuclear particle, and has a coverage in the range of 20-50% defined by formula (1); coverage (%)=(a part of the surface area of the nuclear particle covered by the insulating coating/total surface area of the nuclear particle)×100.
