Abstract
An electrically conductive paste which ensures formation of a dense electrode film even in a low-oxygen-concentration atmosphere without strict control of the atmosphere is described. The electrically conductive paste comprising Cu powder, glass frit and an organic binder resin, wherein the glass frit comprises Zn- and Cu-containing borosilicate glass and in the melt state has a contact angle with respect to Cu of 90° or less as measured in a nitrogen atmosphere.
Claims8
An electronic element comprising:
- an electronic element body having at least one internal electrode;
- and
- at least one external electrode on an outer surface of the electronic element body electrically connected to the internal electrode, wherein the external electrode comprises copper and a Zn- and Cu-containing borosilicate glass having a contact angle in the melt state with respect to Cu of 90° or less measured in a nitrogen atmosphere.
