PROBLEM TO BE SOLVED: To obtain a sulfinamidocarboxylic acid useful as a metal corrosion inhibitor having low toxicity, high safety, low load on an environment and high effect. SOLUTION: This sulfinamidocarboxylic acid (salt) has a residue of a thiazolidine such as dimethylthiazolidine residue, methylthiazolidine residue, thiazolidine residue, etc., a polycarboxylic acid (salt) residue such as a dicarboxylic acid (salt) residue, a tricarboxylic acid (salt) residue, a tetracarboxylic acid (salt) residue. This method for producing the sulfinamide carboxylic acid (salt) is provided. The sulfinamidocarboxylic acid (salt) is useful as a metal corrosion inhibitor.
