COMPOSITE CERAMIC SHEET, METHOD FOR PRODUCING THE SAME, AND METHOD FOR PRODUCING CERAMIC ELECTRONIC COMPONENT BY USING THE SAME

Document Type and Number:

Japanese Patent JP2005029411

Kind Code:

A

Abstract:

To solve the problem that the yields of electronic components are greatly lowered because of rejects due to short circuit caused by a metallic component penetrated into a ceramic sheet.

The composite ceramic sheet is produced by filling the voids of a ceramic sheet comprising a first ceramic powder and a first organic substance and having voids in its inside with ceramic slurry comprising a second ceramic powder and a second organic substance. The method for producing a ceramic electronic component comprises using the composite ceramic sheet. If the composite ceramic sheet is printed with a metallic paste thereon, the sheet can resist to the penetration of the metallic component thereinto. Therefore, rejects due to short circuit can be greatly reduced in ceramic electronic components using the composite ceramic sheet.
