Abstract
A conductive paste for forming external electrodes of a multi-layer ceramic electronic component contains an Ag-based conductive component, an organic vehicle and a glass frit. The glass frit in the conductive paste contains B2O3, SiO2, PbO, and Al2O3. The total content of SiO2 and Al2O3 in the glass frit is in the range of about 40 to 56 molar percent, the SiO2 content being in the range of about 20 to 40 molar percent and the Al2O3 content being in the range of about 12 to 24 molar percent.
