Patent ID: 7510673

Claim:
An electroconductive paste for an external electrode disposed on a surface of a ceramic electronic element characterized by comprising a base-metal electroconductive powder, glass frit, and an organic vehicle, wherein the glass frit comprises: a B 2 0 3 content of 10 to 20 percent by mole; a SiO 2 content of 50 to 65 percent by mole; an alkali metal oxide content of 10 to 20 percent by mole; a ZnO content of 1 to 5 percent by mole; a TiO 2 content of 1 to 5 percent by mole; a ZrO 2 content of 1 to 5 percent by mole; and an Al 2 O 3 content of 1 to 5 percent by mole; wherein the base-metal electroconductive powder comprises a primary component and a spherical secondary component comprising Pd or Au; and wherein the primary component is a 20:80 to 80:20 mixture of a spherical Ag powder having an average particle diameter of 0.5 to 1.0 Î¼m and a flat Ag powder having an average particle diameter of 1.5 to 5.0 Î¼m and an aspect ratio of 5 to 70.
