Summary:PURPOSE:To improve the performance of a flux for soldering by incorporating phosphorous acid compds. having a specific structure into this flux. CONSTITUTION:The flux for soldering is constituted by incorporating at least one kind of the phosphorous acid compds. expressed by the general formula (I). The flux for soldering which has high activity, decreases flux residues, does not contain chlorine ions in the residues and can be easily removed with a harmless solvent, such as IPA, is obtd. according to the general formula (I).
