The present invention relates to a liquefied gas storage tank for storing liquefied gas, comprising: a tank body in which liquefied gas is stored; a heat insulation part formed by laminating and injecting a heat insulating material on the outer surface of the tank body in a spraying manner; and a flow path forming part for forming a leakage path for the movement of the leaked liquefied gas between the tank body and the heat insulation part, wherein the flow path forming part is installed in a region where stress is concentrated during thermal deformation of the tank body, thereby capable of preventing breakage of the heat insulation part.
