An anti-freezing agent composition that suppresses corrosion on metals. An antifreezing component, an oxycarboxylate salt and a polymerized phosphate salt are contained. The antifreeze composition of the present invention has a great effect of suppressing metal corrosion. In particular, it exhibits an excellent effect even under repeated wet and dry conditions simulating the natural environment, and the corrosion rate is equal to or lower than that of water.
