A primary barrier of a cargo tank is disclosed. The primary barrier according to an embodiment of the present invention comprises: a flat part; and longitudinal and transverse long corrugations which are formed in a curved shape protruding from the flat part at uniform intervals to cross each other. One or more short corrugations are formed to protrude laterally from the long corrugations formed between the crossing parts. Therefore, the present invention effectively copes with contraction and expansion caused by thermal stress under extremely low-temperature environment.
