Plural columnar recesses (30) are formed in a depressed form, on one end surface of a solid electrolyte (12) disposed on a side facing an anode (14). Accordingly, the solid electrolyte (12) is formed with a thick-walled portion (32) and thin-walled portions (34), wherein the thick-walled portion (32) extends from an abutment surface with respect to the anode (14) to an abutment surface with respect to a cathode (16). The thin-walled portions (34) extend from the abutment surface with respect to the cathode (16) to the columnar recesses (30), and further have a thickness smaller than that of the thick-walled portion (32). Therefore, the anode (14) also is formed on bottom and side wall surfaces of the columnar recesses (30). In the obtained electrolyte electrode assembly (18), a calculated value of conductance per unit area is set at 2 to 30 S/cm<SUP>2</SUP>. |
