PROBLEM TO BE SOLVED: To suppress generation of a reaction product on an interface at the time of firing and make it possible to fire an air pole at a high temperature. SOLUTION: In this method, a solid electrolyte 1 is coated with a paste containing raw material powder as an air pole material, and a pellet 3 containing (A1-x Bx ) (C1-y Dy )O(3+δ) as main constituent, is placed on this coating film 2 and fired. With this, excess of the elements A, B caused by diffusion of the elements C, D into the solid electrolyte 1 on the interface is supplemented by supplying the elements C, D from the pellet 3 and the excess of the elements A, B is suppressed. Here, one or more of La, Y, Sm, and Gd is used as the A, one or more of Sr, Ba, and Ca as the B, one or more of Mn and Co as the C, one or more of Cr, Ni, Mg, Zr, Ce, Fe, and Al as the D, and 0<=x<=0.50, and 0<=y<=0.50 are given. |
