PROBLEM TO BE SOLVED: To provide a vaporizable rust preventive which does not comprise nitrites producing nitrosoamine damaging the health, also exhibits excellent rust prevention performance not only to cast iron but also to the other steel metals and to nonferrous metals such as copper, zinc and aluminum, and further has noncombustibility. SOLUTION: The vaporizable rust preventive includes: (A) an amine-containing inorganic porous material obtained by impregnating (a1) an inorganic porous material with (a2) an amine compound; (B) benzotriazole and/or tolyl triazole; and (C) at least one selected from the group consisting of metal oxides, metal hydroxides, metal carbonates, metal silicates and metal phosphates at prescribed ratios.
