A fuel battery is formed by stacking an air electrode layer, an electrolyte layer, and a fuel electrode layer and comprises: a plate-like fuel battery cell main body in which a surface of one of the air electrode layer and the fuel electrode layer is defined as a first principal surface and a surface of the other layer is defined as a second principal surface; a first collector contacting the first principal surface; and a second collector contacting the second principal surface. The second collector is set to be more compressively deformable than the first collector. When viewed along the thickness direction of the fuel battery cell main body, at least a part of the boundary of a second region of the second collector, said second region corresponding to the second principal surface, is set to be positioned inside the boundary of a first region of the first collector, said first region corresponding to the first principal surface, and the other boundary of the second region except for the part of the boundary is set to be positioned inside the boundary of the first region or on the boundary of the first region.
