PURPOSE: A liquefied gas storage tank is provided to doubly prevent leakage of liquefied gas by sealing and insulating walls attached in an inner wall of a storage tank, and to reduce space that one storage tank occupy. CONSTITUTION: A liquefied gas storage tank comprises a tank body, a cover, an insulating wall(20), a sealing wall. The insulating wall comprises multiple secondary insulating panels, multiple primary insulating panels, and a secondary gap. The secondary insulating panels are arranged on an inner surface of the tank body of a storage tank. The primary insulating panels are arranged on the secondary insulating panels. The secondary gap is formed between the secondary panels and is covered by the primary insulating panels. The secondary gap is filled with insulating substances and is foamed so that the secondary panels can be integrated each other to prevent secondary leakage of liquefied gas.
