Disclosed is an insulation structure of a liquefied gas storage tank. The insulation structure of a liquefied gas storage tank according to an embodiment of the present invention comprises: a foamed insulation layer covering the outer surface of a storage tank for accommodating liquefied gas; a leakage channel formed on the inner surface of the foamed insulation layer in contact with the outer surface of the storage tank and provided as a path for moving the liquefied gas leaking from the storage tank; a plurality of barrier walls provided to envelop the outer side of the foamed insulation layer; and a plurality of supports for supporting the plurality of barrier walls with a gap from the outer surface of the foamed insulation layer. The leakage channel may include: a coating material applied to the outer surface of the storage tank; and a leakage flow path formed between the outer surface of the coating material and the inner surface of the foamed insulation layer. Therefore, provided is an insulation structure of a liquefied gas storage tank capable of maintaining a stable structure and keeping insulating performance in response to the thermal deformation of a storage tank.
