1. A deposition mask packaging method for packaging a deposition mask having an effective region in which a plurality of through-holes is formed, the deposition mask packaging method comprising:
preparing a receiving portion that has a first opposing surface and a concave portion provided on the first opposing surface and covered with a first flexible film;
obtaining the deposition mask placed on the receiving portion;
arranging a lid portion on the deposition mask such that the receiving portion and the lid portion face each other; and
sandwiching the deposition mask between the receiving portion and the lid portion,
wherein the effective region of the deposition mask is placed on the concave portion with the first flexible film interposed therebetween in the obtaining of the deposition mask,
wherein ends on both sides in a first direction of the deposition mask are arranged on the first opposing surface of the receiving portion in the obtaining of the deposition mask,
wherein an interposed sheet is interposed between the deposition mask and the first flexible film in the step of obtaining the deposition mask, and
wherein a dimension of the interposed sheet in a second direction, orthogonal to the first direction in a plane direction of the deposition mask, is smaller than a dimension of the concave portion in the second direction.
