Abstract

The present invention provides a method for manufacturing a conductive structure having high electrical conductivity, and a method for manufacturing a dimensionally accurate separator for a fuel cell having high electrical conductivity. In the present invention, the cavity surface temperature of a mold is kept equal to or higher than the crystal melting temperature (T) of composite material until the shaping of the composite material melted in the mold is completed, and after the completion of the shaping process, the cavity surface temperature of the mold is controlled to be equal to or higher than a temperature 20° C. lower than the crystallization temperature (T) of the composite material but equal to or lower than a temperature 20° C. higher than the crystallization temperature of the composite material to harden the composite material.
