A manufacturing method of a separator for a fuel cell coupled to both ends of a unit cell so as to support the unit cell includes: a preforming step for forming a preform which is incomplete and similar to a shape of the separator; and a main forming step for forming the preform so as to form the separator. Since the separator is formed through two steps of the preforming step and the main forming step using composite material of mixture of expanded graphite, flaky graphite, and phenolic resin or mixture of expanded graphite, carbon fiber, and phenolic resin, time of the main forming is reduced so that productivity can be enhanced.
