Claim:
A substrate storage container comprising: a container body capable of storing a plurality of substrates in array, a lidding body, and a retainer for retaining substrates therebetween, characterized in that the retainer includes a pair of flexible, elastic pieces that are extended from the interior side of the lidding body in the direction of substrates being stored in the container body and arranged in the direction of the array of a plurality of substrates, and holding groove pieces each formed with the elastic piece for touching and holding the rim of the substrate, wherein the elastic piece with holding groove piece is gradually curved outward with respect to the width direction of the substrate from the interior side of the lidding body toward the substrate, so as to reduce the contact-holding area of the holding groove piece with the rim of the substrate; and wherein the pair of flexible, elastic pieces are, from base to end, extended continuously apart from each other, each of which is convexly curved such that a convex surface of each of the elastic pieces faces the stored substrate.
