A ZINC OR ZINC ALLOY PLATED STEEL SHEET EXPRESSING A PERFORMANCE PROVIDED WITH BOTH CORROSION RESISTANCE AND SURFACE CONDUCTIVITY IS PROVIDED. THE ZINC OR ZINC ALLOY PLATED STEEL SHEET OF THE PRESENT INVENTION IS A ZINC OR ZINC ALLOY PLATED STEEL SHEET HAVING AN ARITHMETIC AVERAGE ROUGHNESS RA OF A ZINC-PLATED LAYER SURFACE DEFINED BY JIS B 0601, OBTAINED BY A STYLUS-TYPE SURFACE ROUGHNESS METER DEFINED BY JIS B 0651, OF 0.3 �M TO 2.0 �M AND A MAXIMUM PEAK HEIGHT RP OF 4.0 �M TO 20.0 �M, WHEREIN THE ARITHMETIC AVERAGE ROUGHNESS RA (PEAK) OBTAINED BY MEASURING A RANGE OF EVALUATION LENGTH OF 20�M OF PEAK PARTS OF 80% OR MORE OF THE RP BY AN ELECTRON BEAM 3D ROUGHNESS ANALYZER IS 70% OR MORE OF THE ARITHMETIC AVERAGE ROUGHNESS RA (AVERAGE) OBTAINED BY MEASURING A RANGE OF EVALUATION LENGTH OF 20 �M OF PARTS OF A HEIGHT OF �20% ABOUT AN AVERAGE LINE, OBTAINED BY A STYLUS-TYPE SURFACE ROUGHNESS METER, BY AN ELECTRON BEAM 3D ROUGHNESS ANALYZER.
