Summary:PURPOSE: A vessel for containing high purity chemical solution with little damage and light weight is provided not to deteriorate quality of the solution and to simply handle and carry the vessel during the delivery and/or preservation thereof. CONSTITUTION: The vessel(1) comprises an inner layer(3) made of high purity resin including at least one selected from a group of ethylene, propylene, butene-1-4-methyl-pentene-1 or octene-1 olefin polymer and ethylene and other olefin copolymer; an intermediate layer(4) made of solvent-proof resin including at least one selected from a group of polyamide, polyvinyl alcohol, poly(ethylene-co-vinyl alcohol), polyester and polyphenylene oxide; and an outer layer(5) made of resin composition including light-shield material. The vessel is produced by blowing formation of all components. All of the layers(3,4,5) have more than 2.0 of minimum light-absorption value and 1.5mm(-1) or more of absorption coefficient at 400nm of wavelength.
