Abstract
A fuel cellincludes a silicon substrate, a porous support material layer, a plurality of holesor columns, and a stacked body. The stacked body includes an upper electrode layer, a solid electrolyte layerand a lower electrode layer. The upper electrode layeris also formed on a surface parallel to a main surface of the silicon substratein a manner of being continuous to the upper electrode layer formed in the plurality of holesor columns, or the lower electrode layeris also formed on a surface parallel to the main surface of the silicon substratein a manner of being continuous to the lower electrode layerformed in the plurality of holesor columns. The stacked body is supported by the porous support material layerin at least upper end portions and lower end portions of the plurality of holesor columns
