PROBLEM TO BE SOLVED: To provide a method for producing a hot dip metal plated steel strip where gas wiping is performed, thus the coating weight of plating is made uniform, also, its appearance properties are improved, and further, productivity can be improved. SOLUTION: A gas is injected from slit nozzles arranged on both the sides of a steel strip to the oblique lower part, the inclined angleαbetween the injection direction of the gas in the gas injection port of each slit nozzle and the horizontal plane is made the same, also, the distance H between the gas injection port of each slit nozzle and the bath face of molten metal is made the same, and the inclined angleαis controlled to 0.9 to 2.0°.
