LAMINATED CERAMIC ELECTRONIC COMPONENT AND METHOD FOR PRODUCING LAMINATED CERAMIC ELECTRONIC COMPONENT

摘要

A laminated ceramic electronic component has a variety of superior mechanical properties and electrical properties, including a high degree of freedom in the design for ceramic materials, and can be manufactured at low cost and with a low percentage of defective products. The laminated ceramic electronic component includes a laminate including a plurality of stacked ceramic layers and a plurality of internal electrodes containing Al as a main constituent, the internal electrodes being arranged along specific interfaces between the ceramic layers, and external electrodes located on an outer surface of the laminate, wherein surface layer sections of the internal electrodes include an Al2O3 layer.
