Abstract
A ceramic component element is provided. The ceramic component element includes: an insulating ceramic base with pores formed on its surface and previously fired; and a functional ceramic sheet bonded to the insulating ceramic base and having electrical characteristics. The functional ceramic sheet is physically bonded to the insulating ceramic base by forming pressing a green sheet for the functional ceramic sheet on the insulating ceramic base at constant temperature and pressure so that parts of the green sheet are forced to put into the pores and anchored, and the functional ceramic sheet is chemically bonded to the insulating ceramic base by firing the anchored green sheet in such a manner that functional oxides of the green sheet penetrate the insulating ceramic base by solid diffusion to form a diffusion bonding layer.
