发明名称 MULTILAYER CERAMIC ELECTRONIC COMPONENT
摘要 The present invention aims to suppress the cracks and delamination to improve the bending strength of multilayer ceramic electronic component with internal electrode layers wherein the thickness of the internal electrode layer is 0.5 μm or less. The multilayer ceramic electronic component is a laminated body having internal electrode layers and dielectric ceramic layers which are laminated alternately. The internal electrode layers have electrode discontinuity portion. In a part of the electrode discontinuity portion, a dielectric ceramic particle bigger than the thickness of the dielectric ceramic layer is contained when the cross section is observed from the direction perpendicular to the laminating plane of the laminated body. The dielectric ceramic particles have the same crystal structure with the dielectric ceramic particles contained in the dielectric ceramic layers, and contact with at least one internal electrode layers which are opposite to each other with dielectric ceramic layers sandwiched therebetween.
