Zusammenfassung:	PURPOSE:To provide a rust preventive multi-ply steel sheet excellent in corrosion resistance and coating adaptability. CONSTITUTION:The multi-ply plated steel sheet is obtained by forming a Zn plated layer at least on one surface of a steel sheet as a 1st layer and a coating layer of >=1g/m by using a Ni-P alloy as a 2nd layer. As a result, the rust preventive multi-ply steel sheet excellent in corrosion resistance and coating adaptability is obtained without necessitating chemical conversion treatment as a treatment before coating.
