Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inspection method for a tubular cell type solid oxide fuel cell (T-SOFC), capable of detecting pin holes in cylindrical cells and superior in reliability. SOLUTION: In inspection, electric wires 10b to 10e for inspection are attached to positive-negative sides and negative-side current collecting rods 41a, 41b and to interconnectors 8 of respective cells 7. The electric wires 10b to 10e are led to a voltmeter 12. Open-circuit potential of each cell 7 can be detected as the the potential difference between the potential of the interconnector or the current collecting rod and cell the potential of one cell before cell and the potential of its own interconnector.
