The present invention relates to an insulation structure of a liquefied gas cargo tank, comprising: a triple insulation portion; a main barrier; an impact absorption portion; a subsidiary barrier; and a fastening portion. The triple insulation portion includes a laminated upper portion insulation panel, a vacuum insulation panel, and a lower portion insulation panel. The main barrier is disposed on the top of the upper portion insulation panel. The impact absorption layer is disposed between the upper portion insulation panel and the vacuum insulation panel. The subsidiary barrier is disposed between the vacuum insulation panel and the lower portion insulation panel. The fastening portion penetrates through the subsidiary barrier, the vacuum insulation panel, and the impact absorption layer, and is coupled to the upper portion insulation panel and the lower portion insulation panel. An object of the present invention is to provide the insulation structure of a liquefied gas cargo tank capable of improving a transferring efficiency of liquefied gas by improving insulation performance.
