A unit cell for a solid electrolyte fuel cell is provided with an air electrode, a fuel electrode, a solid electrolyte sandwiched between the air electrode and the fuel electrode, and a porous metallic base body joined to at lease one of the air electrode and the fuel electrode. The porous metallic base body includes a plurality of porous base body layers stacked to form a laminated structure in which one layer joined to at least one of the air electrode and the fuel electrode has porosity lower than that of the other layer not joined to at least one of the air electrode and the fuel electrode.
