PROBLEM TO BE SOLVED: To provide a heat-curable conductive paste for forming a conductive film excellent in electrical conductivity.SOLUTION: The present invention provides the heat-curable conductive paste which contains a conductive powder, a thermosetting epoxy resin, a curing agent, and a catalyst. The conductive powder is obtained by surface-treating a metal powder as a core with a carboxylic acid or its salt. The curing agent is a compound capable of reacting with the epoxy resin by heating to generate a hydroxyl group. The catalyst is a catalyst allowing an esterification reaction between the carboxylic acid or its salt and the hydroxyl group to proceed.SELECTED DRAWING: Figure 2 |
