Abstract
A multilayer ceramic electronic device includes a plurality of internal electrode layers that face each other; and a plurality of dielectric layers, each of which is sandwiched by each two of the plurality of internal electrode layers. A main component of the plurality of dielectric layers is barium titanate zirconate. In each of the plurality of dielectric layers, an amount of zirconium is 2 at % or more and 14 at % or less with respect a total amount of titanium and zirconium. Curie point of the plurality of dielectric layers is less than 85 degrees C. An average thickness of each of the plurality of dielectric layers is 1 μm or less.
