Ceramic and manufacturing method thereof

The present invention provides a ceramic body comprising a conductor inside the ceramic body and method of manufacturing the water gap between the conductive body and the ceramic body is immersed can be more effectively prevented. In the gap between (11) and the ceramic laminate (10) comprising an internal electrode layer is immersed in the supercritical fluid monomers. Thereafter, polymerization of the monomer, filling voids between the polymer (11) and the ceramic laminate (10) in the internal electrode layers.
