Abstract: A multilayer ceramic electronic component in which an interface of an edge region of an external electrode that extends around to a side surface of a ceramic body and the ceramic configuring a surface of the ceramic body, an inorganic matter is present containing 26 mol % or more and less than 45 mol % of SiO2 and having a molar ratio (TiO2+ZrO2)/(SiO2+TiO2+ZrO2) of 0.154 or more, or an inorganic matter is present containing 45 mol % or more of SiO2 and having a molar ratio (TiO2+ZrO2)/(SiO2+TiO2+ZrO2) of 0.022 or more. Furthermore, the inorganic matter may contain B2O3 having a molar ratio relative to SiO2 within 0.25≤B2O3/SiO2≤0.5.
