Laminated ceramic electronic component and method for producing laminated ceramic electronic component

Abstract

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 Al 2 O 3 layer.

What is claimed is: 
     
         1 . A method for producing a laminated ceramic electronic component, the method comprising the steps of:
 preparing a raw laminate including a plurality of stacked ceramic green sheets and a plurality of metal constituent containing layers containing Al as a main constituent, the layers being formed along specific interfaces between the ceramic green sheets; and   firing the raw laminate at a temperature of about 600° C. to about 1000° C. under an atmosphere with an oxygen partial pressure of about 1×10 −4  MPa or more.   
     
     
         2 . The method for producing a laminated ceramic electronic component according to  claim 1 , wherein an average rate of temperature increase from room temperature up to a firing top temperature is about 100° C./min or more in the firing step.
