Fuel Cell and Method for Producing Same

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