Abstract
An interconnector made of a lanthanum chromite is provided on a fuel electrode of an SOFC, and a P-type semiconductor film which is a conductive ceramics film is formed on a surface of the interconnector. When a maximum value (maximum joining width) of the “lengths of a plurality of portions at which the interconnector and the P-type semiconductor film are brought into contact with each other” on a “line (boundary line) corresponding to an interface between the interconnector and the P-type semiconductor film in a cross section including the interconnector and the P-type semiconductor film” is 40 μm or less, peeling becomes less liable to occur in a portion corresponding to the maximum joining width at the interface.
