PURPOSE:To allow a mutual connection part to hold a satisfactorily high denseness and high conductivity even though the material has undergone a baking process. CONSTITUTION:An air electrode 3 or a fuel cell is provided with a precoat layer 4 of at least 5mum thick and expressed by a chemical formula La1-XM 1X-YM2ZO3, where M1 either of Mg, Sr, Ca, M2 is either of Co, Mn, and x, y, z are to be selected appropriately, and over this precoat layer 4 a mutual connection part 5 is provided. |
