Abstract
A conductive adhesive agent of the invention contains an elution preventing film-forming agent which becomes reactive after electric continuity through a conductive particle appeared in the conductive adhesive agent when a binder resin is being hardened, to thereby form an elution preventing film on a surface of the conductive particle By using this conductive adhesive agent, the packaging structure is made migration resistant and sulfurization resistant.
