LAMINATED CERAMIC ELECTRONIC COMPONENT AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: To provide laminated ceramic electronic parts for which the service life deterioration of the parts caused by the ruggedness of the interfaces between internal electrode layers and ceramic layers and the occurrence of structural defects (delamination, curved electrode sections, etc.), when the thicknesses of the films constituting the parts are reduced or the number of the films is increased can be suppressed, and a method for manufacturing the parts. CONSTITUTION: Laminated ceramic electronic components (a laminated ceramic capacitor) 1 has a structure such that internal electrode layers 8 and 9 are laminated upon another via ceramic layers (dielectric ceramic layers) 2 in a ceramic element 3. Roughness Ra of the interfaces between the electrode layers 8 and 9 and ceramic layers 2 is adjusted to be 200 nm or smaller, and at the same time, the defect (pores) generation rate in the ceramic layers 2 are suppressed to <= 1% in area ratio on the polished cross section produced by polishing the cut end face of the layer 2.
