Abstract

The present invention provides, as a separator for fuel cell which is lightweight, can be easily made thin, and which has superior corrosion resistance and shape stability, a fuel cell 100 containing a separator for fuel cell 10, wherein a conductor pattern 2 is formed on one principal plane 1A of an insulation layer 1 to form a groove for a gas flow path 3 sectioned by the conductor pattern 2 on this principal plane, a conductor terminal 4 is formed on the other principal plane 1B of the insulation layer 1, and this conductor terminal 4 and the conductor pattern 2 are electrically connected by a via hole 5 penetrating the insulation layer 1, and a membrane electrode assembly (complex having an electrolyte membrane and an electrode (fuel electrode, oxygen electrode) laminated thereon) 14 having the separator for fuel cell disposed on both surfaces.
