PROBLEM TO BE SOLVED: To provide a power suppling body improving energy efficiency and reducing a breakage of a solid electrolyte film. SOLUTION: The power feeding bodies (14) and (15) composing an electrolysis cell, of which the one face is located in the side of a solid electrolyte film (10) and of which the other face is located in the side of electrodes (12) and (13) are characterized by; that one face of the power feeding bodies are arranged so as to contact with the solid electrolyte film (10); that the power feeding bodies are formed with two or more power feeding body parts (14A and 14B) and (15A and 15B); and that surface of the first power feeding body parts (14A) and (15A) which forms the one face, has a finer smoothness than a predetermined value, and the second power feeding body parts (14B) and (15B) which forms the other face, has porosity more than a predetermined value. |
