<p>PROBLEM TO BE SOLVED: To provide a conductive paste which can attain easy printing and little running. SOLUTION: This conductive paste involves conductive powder and binder as essential components, whereas 90-98 wt.% of the binder is thermosetting resin and its remainder is thermoplastic acrylic resin. The thermosetting resin consists of macromolecular weight thermosetting resin of weight average molecular weight 3,500-10,000 and low molecular weight thermosetting resin of weight average molecular weight 350-3,500, and the weight average molecular weight of macromolecular weight thermosetting resin is twice or more times the weight average molecular weight of low molecular weight thermosetting resin.</p> |
