Zusammenfassung:Disclosed is a method of producing a hot-dip metal coated steel strip capable of sufficiently suppressing generation of bath wrinkles and producing 5 high-quality hot-dip metal coated steel strip at low cost. The disclosed method of producing a hot-dip metal coated steel strip includes: blowing a gas from a pair of gas wiping nozzles 20A and 20B to a steel strip S while being pulled up from a molten metal bath 14 so as to adjust a coating weight of molten metal on both sides of the steel strip S, in which each of the gas wiping 10 nozzles 20A and 20B includes an injection port portion that is installed downward with respect to a horizontal plane such that an angle formed by the injection port portion and the horizontal plane is 10° or more and 75 or less, and has a header pressure below 30 kPa.
