PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell which has a second intermediate layer having high bonding strength to a first intermediate layer, and to provide a fuel cell module.SOLUTION: The solid oxide fuel cell comprises: a solid electrolyte layer 4; a fuel electrode layer 3 provided on one side of the solid electrolyte layer 4; an air electrode layer 6 provided on the other side of the solid electrolyte layer 4; and an intermediate layer 5 provided between the solid electrolyte layer 4 and the air electrode layer 6. The intermediate layer 5 has a first intermediate layer 5a and a second intermediate layer 5b. The first intermediate layer 5a is provided with a plurality of projections 5a1 formed on a surface of the solid electrolyte layer 4. The second intermediate layer 5b is formed of a porous body. Portions between the plurality of projections 5a1 of the first intermediate layer 5a is filled with a material for forming the second intermediate layer 5b. |
