Abstract: A multilayer ceramic electronic component includes an element body and a terminal electrode. The element body includes internal electrode layers and insulation layers alternately laminated in a lamination direction. The terminal electrode is formed on an outer surface of the element body to be contacted and connected with the internal electrode layers. The terminal electrode includes an end-side electrode part and an upper-side electrode part. The end-side electrode part covers a leading end of the element body where the internal electrode layers are led. The upper-side electrode part is formed on a part of an upper surface of the element body and continues to the end-side electrode part. The terminal electrode is not substantially formed on a lower surface of the element body located on the other side of the upper surface along the lamination direction.
