A zirconia-base solid electrolyte function element comprising a zirconia-base solid electrolyte substrate, wherein a reinforcing layer is formed directly on each side of said zirconia-base solid electrolyte substrate, the ratio of the shrinkage modulus to the zirconia-base electrolyte substrate to the reinforcing layers is 1.01 to 1.08, and the substrate and the reinforcing layers have been sintered simultaneously.

Reinforced electrolyte function elements

A heater including an electron-conductive pattern designed to generate heat, which has a partially and/or entirely stabilized ZrO.sub.2 -base substrate, an Al.sub.2 O.sub.3 -base coating layer disposed on the surface of the substrate, and an electron-conductive pattern to generate heat disposed on the coating layer.
