An average molarity of the Ce within a range from the basing point up to 3 µm toward the solid electrolyte layer 4 is equal to or less than 10 mol% with respect to a total of Ce, Zr, and other rare earth elements, an average molarity of Zr within the range is equal to or more than 70 mol% with respect to a total of Ce, Zr, and other rare earth elements, or a molarity ratio of Ce with respect to Zr within the range is equal to or less than 0.143.",
