PURPOSE: To facilitate formation of a mutually connected part without using vaporization or pressurizing processes by connecting sintered mutual connection material in which calcium and chromium are taken from attached matter on the surface into a structure of LaCrO3 to an air electrode. CONSTITUTION: Mix of grain of LaCrO3 in which elements selected among a group of Sr, Mg, Ca, Ba, Co, and mix of these with salt solution comprising calcium and chromium to form oxide by heat is attached onto a selected part 24 on the surface of an air electrode 16 without using pressurizing operation. The mix is heated again to 800 deg. to form attached matter comprising calcium oxide and chromium oxide on the surface of grain. Grain including the attached matter of oxide on the surface is intermittently heated at temperatures of 1300-1500 deg. in an oxidation atmosphere without using pressurizing operation. Mismatching of thermal expansion of a mutual connection part 26 to the air electrode 16 and electrolyte 18 can thus be reduced. |
