PROBLEM TO BE SOLVED: To provide a cylindrical solid-electrolyte fuel cell such that a cell main body can be easily and surely gas-sealed and the gas seal is easy to check. SOLUTION: An air electrode is formed on one side of a cylindrical solid- electrolyte and a fuel electrode is formed on the other side. A cap-shaped sealing member 11 made of ceramics, which comprises a base bottom part 14 and a cylinder part 13, is fitted over the outer peripheral surface of one end of a cylindrical cell main body 8 via a gas seal layer 9 made of ceramics with a thickness of 70 to 250 μm, the cell main body 8 being electrically connected to the air electrode or the fuel electrode and having a current collector exposed to the outer surface thereof. |
