An average molarity of the Ce within a range from the basing point up to 3 μm toward the solid electrolyte layer 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.",
