ABSTRACT:
The present invention provides a conductive paste and a conductor and a ceramic substrate using the conductive paste which, when used as a conductive material for a ceramic substrate, can prevent cutting of the conductor in a through hole and peeling of the conductor from the through hole side wall during burning, thereby improving the yield and reliability of through hole conduction. The conductive paste contains Cu powder, Ni powder, glass frit and an organic vehicle, the amount of the Ni powder being about 1 to 20% by weight relative to the total amount of the Cu powder and the Ni powder, and the amount of the glass frit being about 1 to 40% by weight relative to the total amount of the Cu powder, the Ni powder and the glass frit.
