PURPOSE: To provide a solid electrolyte for a solid electrolyte fuel cell (SOFC) by forming an oxygen ion conductor thin film with a substrate different from a film forming material and having uniformly distributed small holes and a required single crystal thin film stuck to the substrate. CONSTITUTION: A stabilized zirconia single crystal thin film 2 of a film forming material is stuck to a substrate 1 different from the film forming material by the CVD method or the like. Uniformly distributed multiple small holes 3 are bored on the substrate 1 to form an oxygen ion conductor thin film. Since the sintering method is not used, this thin film has large strength, low electric resistance, and high gas transmission efficiency, the deterioration of the material can be reduced, and the oxygen ion conductor thin film suitable for the solid electrolyte for the SOFC is obtained. |
