Abstract
A multilayer ceramic electronic component includes an element body in which dielectric layers and internal electrode layers having different polarities are laminated alternately. The dielectric layers contain a main component of a perovskite-type compound represented by (Ba1-a-bSraCab)m(Ti1-c-dZrcHfd)O3. 0.94<m<1.1, 0≤a≤1, 0≤b≤1, 0≤c≤1, and 0≤d≤1 are satisfied. The dielectric layers contain a first sub-component of 2.5 mol or more to the main component of 100 mol. The first sub-component contains a boron oxide and/or a lithium oxide. The internal electrode layers contain a main component of copper and/or silver.
