Zusammenfassung:	A rust prevention method for a steel material according to the present application inhibits the corrosion of the steel material due to the adhesion of salt by including a step for directly applying a rust prevention agent comprising a resin, and a layered double hydroxide represented by the chemical formula M2+ 1-xM3+ x(OH)2(NO3 -)x/n・mH2O (M2+ is a bivalent metal, M3+ a trivalent metal; n is a natural number) to a steel material to which salt content has attached. Un procédé de prévention de rouille pour un matériau en acier selon la présente demande inhibe la corrosion du matériau en acier en raison de l'adhérence de sel en incluant une étape d'application directe d'un agent de prévention de rouille comprenant une résine, et un double hydroxyde en couches représenté par la formule chimique M2+ 1-xM3+ x(OH)2(NO3 -)x/n・mH2O (M2+ est un métal bivalent, M3+ un métal trivalent ; n est un nombre naturel) sur un matériau en acier sur lequel un contenu de sel a été fixé. 本願の鋼材の防錆方法は、塩分が付着した鋼材に対し、樹脂と、化学式がＭ2+ 1-xＭ3+ x（ＯＨ）2（ＮＯ3 -）x/n・ｍＨ2Ｏで表される層状複水酸化物（Ｍ2+は２価の金属、Ｍ3+は３価の金属を表し、ｎは自然数である）で表される層状複水酸化物と、を有する防錆剤を直接塗布する工程を含むことで、塩分による鋼材の腐食を抑制する。
