<p><P>PROBLEM TO BE SOLVED: To provide an electrogalvanized steel sheet having both corrosion resistance and high conductivity, and to provide a method for manufacturing the same. <P>SOLUTION: The electrogalvanized steel sheet is manufactured by: forming, on a steel sheet surface, an electrogalvanized layer having a surface height roughness Rz of≥0.60μm measured with a cutoff value of 0.01 mm or an electrogalvanized layer having a surface height roughness Rz of≥0.60μm measured with a cutoff value of 0.01 mm and an orientation index in the (002) plane of <4.0; and forming, on the electrogalvanized layer, an amorphous chemical conversion treatment layer having an average film thickness of≥0.1μm but <0.9μm. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
