Abstract
A substrate storage container includes: a container body molded of molding material in a front open box type for storing substrates; a door element fitted to an opening at the front of the container body; and a compressively deformable gasket for sealing between the container body and the door element. The opening of the container body is projected sidewards and outwards forming a rim portion. A sealing surface for the gasket is formed on an inner surface of the rim portion. The container body is formed with a reinforcing rib directed toward the rim portion. An opposing portion of the reinforcing rib that opposes the rim portion of the container body is reduced in thickness so as to prevent a depression from forming in the sealing surface of the rim portion during molding the container body.
