A liquefied gas storage tank according to one aspect of the present invention stores cryogenic liquefied gas and includes: a primary barrier made of metal that forms a receiving space for containing liquefied gas; a primary insulation member in which a primary insulation panel and a primary insulation material are sequentially disposed on the outside of the primary barrier; a secondary barrier provided outside the primary insulation member; and a secondary insulation member in which a secondary insulation material and a secondary insulation panel are sequentially stacked on the outside of the secondary barrier. The primary insulation material includes primary insulation foam and primary reinforcement. The secondary insulation material includes secondary insulation foam and secondary reinforcement. The density of the primary reinforcement in the primary insulation material may be greater than the density of the secondary reinforcement in the secondary insulation material. Accordingly, the insulation performance of a liquefied gas storage tank can be optimized.
