Patent ID: 7791450

Claim:
A ceramic component comprising: a previously fired insulation ceramic base; a functional ceramic sheet bonded to a surface of the insulation ceramic base by a diffusion bonding layer having an anchoring structure; a pair of internal electrodes embedded into the functional ceramic sheet; and external electrodes electrically connected to the internal electrodes, wherein a functional ceramic paste corresponding to the functional ceramic sheet is applied to the surface of the insulation ceramic base by a printing method and is dried to form a functional ceramic film, the functional ceramic film is pressed against the surface of the insulation ceramic base to anchor the function ceramic film into the insulation ceramic base for secure attachment, and the functional ceramic film is fired to allow functional oxide materials included in the functional ceramic film to permeate the insulation ceramic base by solid diffusion so as to form the diffusion bonding layer and to change the functional ceramic film into the functional ceramic sheet.
