(57) [Problem] To provide a conductor paste which has a low resistance value, does not cause defects such as voids and cracks, and provides a via conductor having excellent quality performance by using a ceramic multilayer substrate technology. To manufacture a ceramic multilayer substrate having excellent quality performance. SOLUTION: A conductive paste 20 containing Ag powder having an average particle diameter of 3 to 10 μm and comprising 95% by weight or more of the entirety of the conductive powder and an organic vehicle, and containing no glass frit, is passed through a via hole of a green sheet 10. Fill into 12, Heat shrinkage suppression sheets 30 on both sides of green sheet laminate S Are laminated and fired to obtain a ceramic multilayer substrate, so that the sintering behavior of the green sheet 10 and the conductive paste 20 is less likely to be shifted. |
