Claim 2:
3. A method of manufacturing a separator member for a fuel cell, the method comprising:
a first resin layer making step of making a first resin layer including a resin; and
a graphite layer making step of making, on the first resin layer, a graphite layer that has a layering amount of 0.5 to 30 g/m2 and is substantially made of graphite having a volume resistivity of 3 mΩ·cm or less,

a material included in the graphite layer includes 95% by weight or more of graphite,
providing a conductive fiber base material and a second resin layer including a resin that are layered between the first resin layer and the graphite layer in order in which the conductive fiber base material is closer to the first resin layer than the second resin layer, and wherein

a thickness of the second resin layer is smaller than a thickness of the first resin layer.
