Abstract
A substrate storage container comprises: a container casing having an aperture through which a plurality of substrates are placed in or taken out; a cover adapted to fit into the aperture of the container casing; a sealing gasket capable of elastic deformation provided between the container casing and the cover; and a retainer, mounted on the cover, capable of retaining the periphery of the substrates. The retainer has: a supporting body mounted on the inside face of the cover; a plurality of elastic pieces provided in elastically deformable fashion on the supporting body; and a block provided on each of the elastic pieces, the block retaining the periphery of one of the substrates. A relation 10.8×w<y<34.3×w is satisfied when a substrate retaining force of each of the elastic pieces is y [unit: N] and a weight per the substrate is w [unit: kg].
