Abstract
A monolithic ceramic electronic component has a ceramic element including a plurality of ceramic layers and a plurality of internal electrode layers. Each internal electrode layer is disposed between two adjacent ceramic layers. The roughness of the interface between each internal electrode layer and each ceramic layer is about 200 nm or less, and the incidence of pores in the ceramic layer is about 1% or less by area at a polished cut cross-section. The monolithic ceramic electronic component can be a monolithic ceramic capacitor, a monolithic ceramic varistor, a monolithic ceramic piezoelectric component or a monolithic substrate.
