Provided is a method by which a polymeric resin can be uniformly adhered to the surface of a metal substrate without creating a residual stress in the metal substrate. This method for forming a covering layer on the surface of a metal substrate includes: forming a resin-containing covering layer on at least a part of the surface of a metal substrate; and thereafter subjecting the covering layer on the surface of the metal substrate to isostatic pressing using a fluid to harden the covering layer. La présente invention concerne un procédé par lequel une résine polymère peut adhérer uniformément à la surface d'un substrat métallique sans générer une contrainte résiduelle dans le substrat métallique. Ce procédé pour former une couche de revêtement sur la surface d'un substrat métallique qui comprend : la formation d'une couche de revêtement contenant une résine sur au moins une partie de la surface d'un substrat métallique ; et ensuite la soumission de la couche de revêtement sur la surface du substrat métallique à un pressage isostatique au moyen d'un fluide pour durcir la couche de revêtement.
