Mask sheet frame body bonding apparatus and manufacturing method of vapor deposition mask

A mask sheet frame body bonding apparatus configured to bond a mask sheet provided with a mask pattern to a frame body, comprising:

• a tension jig configured to hold both end portions of the mask sheet and apply a tensile force to the mask sheet;
• and
• a plurality of pressing members other than the frame body configured to press at least a side of the mask sheet subjected to the tensile force that are opposite to the frame body and are a front face of the mask sheet, between the mask pattern and a holding position of the tension jig,
• wherein the plurality of pressing members are arranged in a direction orthogonal to a direction in which the tensile force is applied,
• a number of the pressing members having a total length corresponding to a width of the mask sheet are configured to press the mask sheet, and
• the plurality of pressing members are provided in a zig-zag shape on at least two shafts.
