PROBLEM TO BE SOLVED: To provide an anticorrosive oil composition containing a solvent, having high anticorrosive property and having little fear for work environment deterioration such as odor and dermopathy or safety such as ignition. SOLUTION: The rust preventive oil composition contains: at least one base oil selected from a group consisting of a mineral oil and a synthetic oil both having a 5% distillation temperature of≥140°C but≤250°C, 95% distillation temperature of≤250°C, a difference between the 5% distillation temperature and the 95% distillation temperature of≤90°C, an aromatic component content of≤5 vol.%, a naphthene content of≥30 vol.% but≤95 vol%, a density of≥0.75 g/cm<SP>3</SP>at 15°C, and a kinematic viscosity of≥0.3 to≤5.0 mm<SP>2</SP>/s at 40°C; at least one kind of a base oil selected from a group consisting of a mineral oil and a synthetic oil both having a 5% distillation temperature of≥260°C and a kinematic viscosity of≥6.0 to≤600 mm<SP>2</SP>/s at 40°C; and an anticorrosive additive.
