There is provided a solid oxide fuel cell module comprising a substrate with an internal fuel flow part provided therein, at least a face thereof, in contact with cells, and interconnectors, being an insulator, a plurality of the cells each made of an anode, an electrolyte, and a cathode, stacked in sequence, formed on a surface of the substrate, and the interconnectors each electrically connecting in series the cells adjacent to each other, wherein the respective cells are varied in area along the direction of fuel flow, and solid oxide fuel cell bundled modules using the same. With the solid oxide fuel cell module of a multi-segment type, according to the invention, it is possible to aim at higher voltage and to attain an improvement in power generation efficiency and current collecting efficiency.
