摘要：
The disclosure provides a fuel-cell separator excellent in conductivity and a method for producing the separator.
A fuel-cell separator comprising a metal substrate and a surface layer formed on a surface of the substrate, wherein the surface layer comprises an antimony-containing tin oxide film in an outermost surface thereof, and the antimony-containing tin oxide film has a value (%) representing orientation of the (200) plane and calculated in accordance with Expression (1): [ Mathematical Expression 1 ] Peak intensity of ( 200 ) plane / 21 Peak intensity of ( 110 ) plane / 100 + peak intensity of ( 101 ) plane / 75 + peak intensity of ( 200 ) plane / 21 × 100 Expression ( 1 ) where individual peak intensity values are obtained by X-ray diffraction, of 35 or more.
