A fuel cell capable of providing an SOFC wherein a thermal cycle resistance is difficult to occur becase of a uniform the flow and distribution of air and fuel gas in cells. When a gas passage hole part having a center through-hole for gas passage provided at the axial center part of a substrate and having a plurality of peripheral through-holes for gas passage disposed symmetrically with respect to the center through-hole is formed, stacked cell substrates can be supported and tightened by the gas passage hole part at the center part. The flows of fuel gas and oxidizer gas can be optimized, and gas distributions can be made uniform. Particularly, temperature distributions can be uniform in radial direction, and a thermal stress due to thermal expansion occur less. A gas separate plate is formed by forming a gas passage pattern by etching both surfaces of a metal substrate.
