(57) [Problem] To provide a high-strength hot-dip galvanized steel sheet having excellent ductility and improved plating adhesion during non-plating and high working, and a method for producing the same. SOLUTION: Al: 0.001 to 0.5%, Mn: 0.001-2%, Fe: 5-20 if necessary %, And the balance is a hot-dip galvanized steel sheet having a plating layer composed of Zn and unavoidable impurities, wherein the Si content of the steel: X (%), the Mn content of the steel: Y (%), the Al of the steel Content: Z (%), Al content of plating layer: A (%), The Mn content of the plating layer: B (%) satisfies the following formula (I), and the microstructure of the steel sheet has a volume fraction of an average grain size of 2 70-97% ferrite of 0 μm or less, average particle size of 10 A high-strength hot-dip galvanized steel sheet comprising 3 to 30% of austenite and / or martensite of μm or less. 3- (X + Y / 10 + Z / 3) -12.5 × (AB) ≧ 0 (1) |
