To provide an electroconductive resin cured product in which a high connection reliabilty can be acquired.

The electroconductive resin composition for electrically connecting between conductive materials contains an electroconductive powder and a resin material which, after adsorbing on the surface of the conductive material, attains an increase amount in the work function on the above surface of the conductive material to 0.6 eV or less, consequently increasing the value of the Schottky electrical current flowing by the way of the resin material, and is characterized in that the above resin material contains an epoxy resin consisting of a straight-chained hydrocarbon and glycidyl ether.
