An anisotropic electric conducting adhesive agent is disclosed; in which electric conducting particles are dispersed in an epoxy based adhesive agent containing an epoxy compound and a curing agent. The mathematic expressions (1) to (5) are satisfied when taking the elastic modului of the cured product thereof at 35 degrees Celsius, 55 degrees Celsius, 95 degrees Celsius and 150 degrees Celsius as EM.sup.35, EM.sup.55, EM.sup.95 and EM.sup.150, respectively, and the variation rate of the elastic modulus measured in the temperature range between 55 degrees Celsius and 95 degrees Celsius as Δ EM .sup.55 to 95, the variation rate of elastic modulus measured in the temperature range between 95 degrees Celsius and 150 degrees Celsius as Δ EM.sup.55 to 95. 700MPa≤ EM.sup.35≤ 3000MPa (1) EM.sup.150< EM.sup.95< EM.sup.55< EM.sup.35 (2)Δ EM.sup.55-95< Δ EM.sup.95-150 (3)20%≤ Δ EM.sup.55-95 (4)40%≤ Δ EM.sup.95-150 (5). |
