FUEL CELL

PROBLEM TO BE SOLVED: To provide a fuel cell with improved reliability for securing an insulation property between conductive members.SOLUTION: A fuel cell 40 comprises: a flat plate-like fuel battery cell body 44 having an air electrode layer 55, an electrolyte layer 56 and a fuel electrode layer 57; a first plate-like conductive member 41 electrically connected to the air electrode layer; a second plate-like conductive member 45 electrically connected to the fuel electrode layer; and a plate-like insulation member 52 arranged between the first and second conductive members. The fuel cell body, the first and second conductive members, and the insulation member 52 are integrally laminated in a thickness direction, and the insulation member 52 has an outer peripheral part extending across an entire periphery in a plane direction beyond any of the outer peripheries of the first and second conductive members.
