A solid oxide fuel cell including a flat plate-shaped solid oxide fuel cell element. The cell element is composed of an ion-conductive ceramic plate formed with ribs connected with each other in a plane, an air electrode formed on one main surface of the ion-conductive ceramic plate, and a fuel electrode formed on the other main surface of the ion-conductive ceramic plate. In producing the fuel cell, a flat plate-shaped green sheet made of an ion-conductive ceramic molding material is press contacted with a rib-forming green sheet made of a material of the same kind and having a unitary shape formed by connecting elongated portions to each other. The contacted green sheets are sintered together to form an ion-conductive ceramic plate. In an alternative, a flat plate-shaped green sheet and a rib-forming green sheet may be separately sintered and then bonded with each other to form an ion-conductive ceramic plate. The ion-conductive ceramic plate is formed with an air electrode surface and a fuel electrode on opposite main surfaces, respectively.
