A method for manufacturing a fuel cell separator ( 18 ) for sandwiching from both sides via diffusion layers ( 15, 16 ) an anode ( 13 ) and a cathode ( 14 ) disposed on an electrolyte membrane ( 12 ). This manufacturing method includes mixing a thermoplastic resin ( 46 ) and a conductive material ( 45 ) to make a mixture ( 50 ), forming a separator starting material ( 68 ) with the mixture, and irradiating a contact face ( 20 b, 30 b) of this separator starting material with an electron beam ( 72 ), hardening the contact face of the separator. Even when reaction heat is produced in the fuel cell ( 10 ), elasticity of the separator contact face is ensured.
