A corner structure of an LNG(Liquefied Natural Gas) storage tank is provided to enable a corner part to efficiently remove a mechanical stress generated in the storage tank. In a conner structure of an LNG(Liquefied Natural Gas) storage tank, an insulation wall is installed at an inner surface of the storage tank storing LNG and forms an insulation layer. A plurality of sealing films is installed at an upper part of the insulation wall and is in contact with the LNG. A corner structure is installed at the edge of storage tank for supporting the sealing films. The corner structure includes a corner member(101) connecting and fixing between the sealing films and the inner surface of the storage tank and an insulating material formed around the corner member. The corner member includes a fixing member(110) fixed at the inner surface of edge of the storage tank and a movable member(130) supported to be capable of a linear movement on the fixing member.
