Abstract
A multilayer ceramic electronic component includes a ceramic element body formed by alternately laminating dielectric layers and internal electrode layers. The dielectric layers include a main component containing barium titanate and a sub-component containing boron oxide and/or lithium oxide. The internal electrode layers include a main component of copper and/or silver. A coverage ratio of the internal electrode layers to the dielectric layers is 98% or less.
