GALVANIZED STEEL SHEET AND PRODUCTION METHOD THEREFOR

Provided is a galvanized steel sheet more highly excellent in terms of punchability.A galvanized steel sheet having a chemical composition containing, by mass%, C: 0.08% to 0.20%, Si: 0.5% or less, Mn: 0.8% to 1.8%, P: 0.10% or less, S: 0.030% or less, Al: 0.10% or less, N: 0.010% or less, one, two, or all of Ti: 0.01% to 0.3%, Nb: 0.01% to 0.1%, and V: 0.01% to 1.0%, in which the relationship (Ti/48 + Nb/93 + V/51) × 12 ≥ 0.07 is satisfied, and a balance of Fe and inevitable impurities, and a microstructure including a ferrite phase and a tempered bainite phase in a total amount of 95% or more in terms of area ratio, in which the average grain diameter of the microstructure is 5.0 µm or less, in which the amount of Fe precipitated is 0.10 mass% or more, in which the amount of Ti, Nb, and V precipitated in the form of precipitates having a grain diameter of less than 20 nm is 0.025 mass% or more in terms of precipitate C equivalent, and in which half or more of precipitates having a grain diameter of less than 20 nm are formed at random.
