PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell, in which an air electrode and an interconnector are firmly fixed and conductivity between the air electrode and the interconnector is excellent, and a manufacturing method of the solid oxide fuel cell.SOLUTION: A solid oxide fuel cell includes: a unit cell including a solid electrolyte layer, a fuel electrode formed on one surface of the solid electrolyte layer, and an air electrode formed on the other surface of the solid electrolyte layer; and an interconnector arranged for the air electrode on a side opposite to the solid electrolyte layer, with the air electrode and the interconnector being bonded by a conductive bonding agent. The conductive bonding agent includes a conductive oxide whose particles are coarse, a conductive oxide whose particles are fine, and a metallic oxide derived from a sintering aid, with an average particle diameter A of the coarse-particle conductive oxide, an average particle diameter B of the sintering-aid-derived metallic
