摘要： PROBLEM TO BE SOLVED: To provide a solid electrolyte fuel cell in which delamination between an electrode layer and an electrolyte layer almost does not occur, and which is superior in heat resistance in using at high temperatures and a thermal impact resistance in temperature rise/temperature fall, and in which an effectual electrode area is increased and a power generation property is improved. SOLUTION: The electrolyte layer 2 is composed of a laminated structure sandwiched between one electrode layer 3 and another electrode layer 4, and on the counter face 3a of one electrode layer 3, a network structure layer 7 for unevenness formation composed of a plurality of first filaments 5 which are directly installed on this counter face 3a and nearly in parallel with each other, and a plurality of second wire-shaped articles 6 which are installed having an appropriate angle against the first wire-shaped article 5 and nearly parallel with each other on this first wire-shaped article 5 and the counter face 3a. Because the effectual electrode area is expanded, the power generation property of a battery can be enhanced, adhesiveness between layers is improved by increasing a junction area, and because the generation of a crack and crevice on the interface of the electrolyte layer and the electrode layer and every crack of the electrolyte layer and the electrode layer can be evaded, the heat resistance and thermal shock resistance can be improved, and thereby, the solid electrolyte fuel cell 1 in which start and stop are rapidly and frequently carried out, is obtained.
