The present invention relates to an insulation structure of a liquefied gas storage tank, which is for securing the thermal insulation performance of the liquefied gas storage tank by spraying a thermal insulating material from the outside of a tank body, including a thermal insulating layer formed by being sprayed on the outside of the tank body. The thermal insulating layer includes two thermal insulating materials having different densities, and the thermal insulating layer comprises: a first thermal insulation unit formed by spraying a thermal insulating material having a relatively high density between two thermal insulating materials having different densities; and a second thermal insulation unit formed by spraying a thermal insulating material having a lower density between two thermal insulating materials having different densities. The present invention forms the thermal insulating layer using two thermal insulating materials having different densities and, by partially spraying the thermal insulating material having a relatively higher density on the outer surface of the tank body to form the first thermal insulation unit, satisfies the load conditions required for cryogenic liquefied gas storage tanks while maintaining thermal insulation performance.
