PROBLEM TO BE SOLVED: To provide an electroplating liquid composition capable of obtaining plating having excellent adhesion with a coating film and also having excellent corrosion resistance even without performing surface treatment. SOLUTION: The organic high polymer composite electrogalvanizing liquid composition comprises: (A) Zn ions by 1 to 600 g/l; (B) iron group element ions by 1 to 600 g/l; (C) at least one kind of phosphoric compound selected from the group consisting of phosphorus-containing oxo acids and their salts by 0.1 to 200 g/l as P ions; and (D) a water soluble or water dispersible organic high polymer compound with the number average molecular weight of 1,000 to 1000,000 by 0.5 to 500 g/l.
