The present invention is a secondary barrier for a liquefied gas storage tank, comprising: a blocking layer comprising at least one polymer selected from a group consisting of polyethylene, polyethylene terephthalate, polyvinyl alcohol, ethylene vinyl alcohol and nylon; and a fiber layer laminated on both sides of the blocking layer, wherein the fiber layer is fixed by an adhesive layer. An objective of the present invention is to provide the secondary barrier that exhibits excellent tensile strength and shear strength even in a cryogenic environment using a blocking layer containing a polymer that does not cause corrosion, and a method for manufacturing the same.
