Abstract: An object of the present invention is to provide a fuel cell preventing formation of a diffusion layer containing Ca and other elements, and having an excellent power generation performance at low temperature by preventing breakdown of a crystal structure of an electrolyte by firing. Disclosed is a solid oxide fuel cell which includes an inner electrode, a solid electrolyte, and an outer electrode, each being sequentially laminated on the surface of a porous support. The porous support contains forsterite, and has a Mg/Si molar ratio of 1.90 to 2.2 both inclusive, and an A-to-B ratio (A/B) of 0.0% to 9.0% both inclusive, where A denotes a maximum peak height which appears at a diffraction angle 2θ=26.5° to 27.0° and B denotes a maximum peak height which appears at 36.5° to 37.0° in a powder X-ray diffraction pattern obtained by using Cu-Kα radiation.
