PROBLEM TO BE SOLVED: To provide a zinc-base-plated steel sheet onto the surface of which a molten metal scattered by spot welding or arc welding hardly deposits. SOLUTION: The zinc-base-plated steel sheet has an oxide layer existing on at least one side of the surface of the plated layer, which has a bulk height of 100-2,000 nm when measured through observation for the cross section and has 3Zn(OH)<SB>2</SB>-ZnSO<SB>4</SB>-xH<SB>2</SB>O. The oxide layer has 3Zn(OH)<SB>2</SB>-ZnSO<SB>4</SB>-3 to 5H<SB>2</SB>O. COPYRIGHT: (C)2010,JPO&INPIT |
