The present invention relates to a heat insulation structure of a liquefied gas storage tank for insulating liquefied gas stored inside a tank body. According to the present invention, the heat insulation structure of a liquefied gas storage tank comprises: a sheet part installed on an outer surface of the tank body to surround the tank body; a fixing part for fixing the sheet part to the outer surface of the tank body; a high-density spray insulation layer formed around the fixing part; and a heat insulation part formed by spraying on the sheet part to include the high-density spray insulation layer. The sheet part includes a composite material sheet capable of being liquid-tight.
