Method for producing hot-pressed member
A method for producing a hot-pressed member includes heating a coated steel sheet, which includes, on a surface thereof, a Zn—Ni alloy coating layer containing 10% by mass or more and less than 13% by mass of Ni at a coating weight of over 50 g/m2 per side of the steel sheet, in a temperature region of an Ac3 transformation point to 1200° C. at an average heating rate of 12° C./second or more, and then hot-pressing the steel sheet.
