PROBLEM TO BE SOLVED: To provide a fuel battery which ensures stable air supply to improve power generation efficiency. SOLUTION: The fuel battery includes a plurality of unit cells 11 each composed of a pair of sheets each having an electrolytic film 12, a first conductive film serving as a fuel electrode 13 disposed on one side of the electrolytic film 12, a second conductive film serving as an oxygen electrode 14 disposed on the other side of the electrolytic film 12, and a through-hole 16, the pair of sheets so fixed to each other at inner peripheries 19 of the sheets that the first conductive films or second conductive films of the sheets face each other, respectively. The fuel battery also includes hollows 25, 26, and 27 which are formed by fixing the unit cells 11 to each other at outer peripheries of the sheets of respective unit cells 11. The hollows 25, 26, and 27 have channel change members 21 that change the flow of an oxygen-containing gas or fuel supplied through the through-holes 16, and at least part of each channel change member 21 is fixed at the outer periphery.
