Abstract
An electrically conductive paste for use as a conductive material for the production of multi-layered ceramic substrates is formed with an organic vehicle and electrically conductive Cu particles mixed with Ag or Bi particles at a rate within a specified range. An electrically conductive material is obtained by subjecting such a paste to a firing process. A multi-layered ceramic substrate is obtained by forming circuits on ceramic sheets with such a paste, stacking them one on top of another and subjecting the layered structure to a firing process.
