SOLID OXIDE FUEL CELL AND INTER-CONNECTOR

A solid oxide fuel cell includes a fuel cell body and an inter-connector. The inter-connector has a base portion and a plurality of projecting portions projecting from the base portion toward the fuel cell body and electrically connected to the fuel cell body, and is integrally formed from a metallic material. Each of the projecting portions has a contour composed of a pair of linear portions which are disposed parallel to each other and each of which includes a straight line, and a pair of curved portions which connect opposite ends of the linear portions.
