LAMINATED BODY FOR FUEL CELL

The invention provides a laminated body for fuel cell having an outer peripheral shape corresponding to an outer peripheral shape of a fuel battery cell and including a resin substrate film and a heat seal layer disposed on each of both surfaces of the resin substrate film, wherein the resin substrate film has a storage elastic modulus of 2,000-8000 MPa, an average thickness of 30-300 μm, a maximum value T1and a minimum value T1of a thickness of the resin substrate film that satisfies the relationship of T1−T1≤12 μm, and a maximum value T2and a minimum value T2of an average value of thicknesses of the resin substrate film that satisfies the relationship of T2−T2≤6 μm, and wherein the heat seal layer has an average thickness of 25-100 μm.
