A clean container having an elastic positioning structure includes a support element and a back positioning element on a base. A cover is disposed for covering the base, and a positioning part is disposed between the cover and the base, which has two elastic arms extended laterally, and each elastic arm extends with a pushing surface respectively. When a plate of brittle material is placed on the base, and the cover is closed, the pushing surfaces are elastically pressed against and push the plate respectively, so that the plate moves backwards and presses against the back positioning element. Therefore, the plate is prevented from being damaged. Additionally, the base, the cover, and the positioning part are made of a conductive material, so that the electrostatic charges for the plate is conducted out of the clean container, and has a protective function of an electrostatic discharge.
