PROBLEM TO BE SOLVED: To increase viscosity by storage or conductivity even when copper, copper alloy, silver-coated copper coated with silver or copper-coated copper alloy coated with silver is used as the conductive powder. The thermosetting electroconductive paste composition which prevents the fall of property and has the outstanding storage stability is provided. A thermosetting conductive paste composition comprising (A) conductive powder, (B) a thermosetting resin, (C) a curing agent, and (D) an inorganic ion exchanger. (A) As the conductive powder, at least one selected from the group consisting of copper, copper alloy, silver-coated copper, and silver-coated copper alloy is used, and (B) a blocked polyisocyanate compound as a thermosetting resin Or a thermosetting conductive paste composition containing a blocked polyisocyanate compound and an epoxy resin.
