and subjecting a surface of said molded article to laser irradiation treatment wherein said laser irradiation conditions are a power of 100 to 200 W and a pulse duration of 30 to 200 ns; wherein said fuel cell separator possesses characteristics to below: residues from laser irradiation on a surface of the separator, expressed as an area ratio, of 5% or less as determined using an optical microscope in accordance with paragraph point of the description; an arithmetic mean roughness Ra at the separator surface of from 0.80 to 1.50 μm wherein said arithmetic mean roughness Ra is measured using a surface roughness tester having a probe tip diameter of 5 μm; a static contact angle at the separator surface of from 15 to 60° wherein said static contact angle is measured using a CA-DT A contact angle meter from Kywa Interface Science Co., Ltd; a contact resistance at the separator surface of from 3 to 7 mΩ·cm 2 as determined according to the contact resistance method in accordance with paragraph point of the description; an electrical conductivity by leachate obtained after immersing the separator for 168 hours in ion-exchanged water at 90°C, under conditions where the weight ratio of ion-exchanged water to separator = 9:1, of 1.2 μS/cm or less wherein said electrical conductivity is measured at 25 to 30°C; and changes in surface roughness after 2,000 hours of immersion in, respectively, 90°C ion-exchanged water and 150°C ion-exchanged water, which are each within 0.3 μm of the surface roughness prior to immersion wherein said changes in surface roughness are measured using a surface roughness tester having a tip probe diameter of 5 μm. molding a composition comprising a graphite powder, an epoxy resin, a phenolic resin, a curing accelerator and an internal mold release agent to form a molded article wherein the phenolic resin is in an amount which is from 0.98 to 1.02 hydroxyl equivalents per equivalent of the epoxy resin;
