SOLID OXIDE FUEL CELL

An object is to provide a solid oxide fuel cell which has an increased gas utilization factor at a cathode layer or an anode layer. A solid oxide fuel cell includes a fuel cell main body which includes a cathode layer, a solid electrolyte layer, and an anode layer and which has a power generation function; a connector disposed to face one electrode layer of the cathode layer and the anode layer; a current collector which is disposed between the one electrode layer and the connector and which is in contact with a surface of the one electrode layer and a surface of the connector, the surfaces facing each other, to thereby electrically connect the one electrode layer and the connector; and a groove provided in a portion of a surface of the one electrode layer, which surface is located on the side where the one electrode layer is in contact with the current collector, the portion of the surface being not in contact with the current collector.
