Abstract
A solid oxide fuel cell includes an Si support substrate having a through hole, an electrolyte film formed on the surface of an Si support substrate and containing a solid oxide having oxygen ion conductivity, a first electrode formed on a surface of the electrolyte film (surface on the side opposite to the Si support substrate), and a second electrode formed at least on a surface exposed from the through hole in a rear face of the electrolyte film. The electrolyte film includes a porous layer including the solid oxide and containing pores inside, a first dense layer formed on a surface of the porous layer (surface on the side opposite to the Si support substrate), and a second dense layer formed at the interface between a rear face of the porous layer and the Si support substrate.
