Abstract
The sealability against interior positive pressure is ensured, while reducing particles generated by friction in opening and closing a lid. Disclosed is a substrate storage container, including: a container body configured to store at least one substrate; and a lid configured to close an opening of the container body. In the substrate storage container, a first part of the container body, the first part being provided around the opening, is non-contact at least partially with a second part of the lid, the second part being opposed to the first part; and the first part and the second part cooperatively form a labyrinth seal structure.
