Abstract:
A highly moisture resistant dielectric ceramic is prepared by providing a compact containing a dielectric ceramic component powder and a second powder including a compound containing an alkali metal element, and firing the compact and a second composition containing an alkali metal element at the same time. A laminated ceramic capacitor using the dielectric ceramic is described.
