The purpose of the present invention is to provide an electroconductive copper paste that can be hardened in an air atmosphere, the pot life being long, the specific resistance being low even when under high-temperature short-duration hardening conditions, and the specific resistance after hardening not varying greatly according to the copper powder content. An electroconductive copper paste characterized in containing (A) a copper powder, (B) a thermoset resin, (C) a fatty acid in liquid form at room temperature, and (D) triethanolamine. Component (B) is preferably a resol-type phenolic resin and, more preferably, component (B) is present in an amount of 10-20 mass parts per 100 mass parts in total of components (A) and (B). |
