PROBLEM TO BE SOLVED: To provide a rust preventive composition excellent in workability and rust prevention performance with suppressing a volatile organic solvent at low, and hardly causing drippings even when coated by a thick film.SOLUTION: There is provided a rust preventive composition containing a rust prevention agent, a wax, a hardened oil and a diluent, and further bentonite of 2 to 6 mass% of the whole composition. It is preferable to contain the rust prevention agent with the amount in a range of 12 to 39 mass% of the whole composition and the diluent with the amount in a range of 15 to 58 mass% of the whole composition. 【課題】揮発する有機溶剤を低く抑えながら、作業性および防錆性能に優れ、かつ厚膜で塗布した場合であってもタレを生じないような防錆組成物を提供すること。【解決手段】防錆添加剤、ワックス、硬化油および希釈剤を含む防錆組成物であって、さらにベントナイトを組成物全体に対して２〜６質量％含む、前記防錆組成物。防錆添加剤は組成物全体に対して１２〜３９質量％の範囲の量で含まれることが好ましく、希釈剤は組成物全体に対して１５〜５８質量％の範囲の量で含まれることが好ましい。【選択図】なし
