Summary:A mask safekeeping case is provided to prevent the generation of damage and defects on a surface of a mask by reducing a contact part of a mask. A first cover(100) is formed to support and fix an upper part of a received mask. A second cover(200) corresponds to the first cover and is formed to support and fix a lower part of the received mask. A loading rib(300) is protruded from bottom surfaces of the first cover and the second cover. The loading rib includes a loading part which comes in contact with a horizontal edge of the mask in a line contact manner. The loading part includes a vertical slope portion for forming an acute angle to a vertical surface of the mask on the basis of a horizontal boundary corresponding to a horizontal edge of the mask, and a horizontal slope portion for forming an acute angle to the horizontal surface of the mask.
