Abstract

A substrate storage container comprises a container body that stores substrates, a lid that closes an opening of the container body, locking mechanisms provided on the lid and locking with the locking portions of the container body, and packing interposed between the container body and the lid, wherein the packing includes a first packing attached to the container body and a second packing attached to the lid, and wherein the first packing and the second packing are located inside the container body from positions of the locking portions when viewed from the direction orthogonal to the closing direction of the lid. As a result, a substrate storage container with improved internal cleanliness can be provided while also improving the sealability with respect to internal negative pressure and positive pressure.
