PROBLEM TO BE SOLVED: To provide a cylindrical fuel cell which can prevent a leakage of a fuel gas from an interface with which a solid electrolyte layer and a power collecting layer are jointed. SOLUTION: A notch 50 is formed in a part of a solid electrolyte 31 to expose a part of an air electrode 32 formed on an inner surface of the solid electrolyte 31, and a collector 35 is laminated and formed on this exposed surface 37 and on both end parts 40 and 41 of the solid electrolyte 31 in the vicinity of the notch 50 so as to have widths d1 and d2, overlap of 1.5-2.5 mm of the power collector 35 with both the end parts 40 and 41 of the solid electrolyte 31 in the circumferential direction. |
