The present invention is directed to a method for manufacturing a vapor deposition mask (2) which includes a mask section (3) and a mask frame (4). The mask section (3) includes an alloy containing iron and nickel. The method includes a heat treatment step of carrying out heat treatment with respect to the mask section (3) in a state in which end parts of the mask section (3) are fixed to the mask frame (4) while tension is applied to the mask section (3).

A coating system for coating a part (10), such as a turbine blade or vane, has a mask (14) positioned adjacent to a first portion (16) of the part (10) to be coated and a mechanism (30) for moving the mask (14) relative to the part (10). The mechanism (30) may be a gear mechanism or a magnetic mechanism.

The object of the present invention is to provide a metal plate capable of manufacturing a deposition mask in which dispersion of positions of through-holes is restrained. A thermal recovery rate is defined as parts per million of a difference a distance between to measurement points on a sample before a heat treatment and a distance therebetween after the heat treatment, relative to the distance therebetween before the heat treatment. In this case, an average value of the thermal recovery rates of the respective samples is not less than −10 ppm and not more than +10 ppm, and (2) a dispersion of the thermal recovery rates of the respective samples is not more than 20 ppm.
