PROBLEM TO BE SOLVED: To suppress swelling of the molded article with water by increasing a water-absorbing resistance of a fiber-reinforced resin molded article composed of a composite of an alamide fiber and a cross-linked polyamino amide. SOLUTION: A coated film of a cured phenol resin is formed on a surface of a fiber-reinforced resin molded article. The fiber-reinforced resin molded article is, for example, a resin gear 2, and the gear is supported by a rotating cylinder 1 and the lower half part thereof is dipped in a phenol resin vanish 3, under which condition the resin gear 2 is rotated to coat the phenol resin vanish 3 on the whole surface of the resin part of the gear. Then, the resin gear under supported by the rotating cylinder is taken out from the phenol resin vanish and rotated at a higher speed than in the dipping process so as to remove a solvent and an excess amount of the phenol resin by centrifugal force. After the process, the article is dried under heating to proceed a curing reaction to form a cured phenol resin coating film on the surface of a resin part of the gear.
