CONDUCTIVE PASTE AND METHOD FOR PRODUCING THE SAME, BASE MATERIAL WITH CONDUCTIVE FILM, AND METHOD FOR MANUFACTURING BASE MATERIAL WITH CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a conductive paste capable of forming a conductive film low in volume resistivity and having excellent thermal cycle durability.

SOLUTION: A conductive paste contains: a copper particle (A); at least one kind of sugar (B) selected from the group consisting of aldose and ketohexose, which are monosaccharides, and polysaccharides in which carbon at the 1-position based on an IUPAC naming method is asymmetric carbon having a hydroxyl group; and a thermosetting resin (C). The conductive paste further contains an ester or amide (D) of organic acid having a pKa of 1-4. A conductive film can be formed by coating the conductive paste on a base material and then heating the conductive paste at a temperature below 150°C to be hardened.
