Electroconductive paste and ceramic electronic component including electroconductive paste

摘要

For mounting on a substrate by using an electroconductive adhesive, an electroconductive paste for forming an external electrode which has improved moisture resistance and which is resistant to occurrence of external-electrode peeling, as well as a ceramic electronic component including the electroconductive paste are provided. The electroconductive paste includes a base-metal electroconductive powder, first glass frit, and an organic vehicle, wherein the first glass frit has a B₂O₃ content of 10 to 20 percent by mole, a SiO₂ 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 TiO₂ content of 1 to 5 percent by mole, a ZrO₂ content of 1 to 5 percent by mole, and an Al₂O₃ content of 1 to 5 percent by mole.
