Zusammenfassung:	PURPOSE:To prevent the short circuit between electrodes or between wirings even if an electric field is applied to it under high conductive and hot and humid atmosphere by containing specified ingredients in conductive paste. CONSTITUTION:Conductive paste contains flake-shaped silver powder, copper powder, ceramic powder, and a kind of nitrophenyl hydrazine. Hereby, high conductive paste, where the resistance of a through hole in a wiring board is low, can be gotten. Moreover, economical conductive paste, where the drop of insulation resistance between through holes after load test in humidity is low and further the quantity of used silver is mail, can be gotten by using flake-shaped silver powder, copper powder, and ceramic powder jointly.
