Disclosed is a thermal insulation structure of a liquefied gas storage tank for a ship with improved structural stability. According to one embodiment of the present invention, the thermal insulation structure of a liquefied gas storage tank for a ship may comprise: a foam insulation layer covering an outer surface of the storage tank for accommodating liquefied gas; a leakage channel formed on an inner surface of the foam insulation layer in contact with the outer surface of the storage tank and provided as a passage for liquefied gas leaking from the storage tank to move; a plurality of barriers provided to surround the outside of the foam insulation layer; a plurality of supports for supporting the plurality of barriers by spacing the barriers apart from an outer surface of the foam insulation layer; a powder insulation material filled between the outer surface of the foam insulation layer and inner surfaces of the plurality of barriers; and fastening parts for fixing and supporting each support to the storage tank.
