    Abstract: Provided is a vacuum insulation panel including a core material and a covering material on an outer side of the core material. The covering material forms an internal space in which the core material is accommodated, wherein the core material includes a first plate in the internal space and having a first thickness. The core material includes a second plate in the internal space, spaced from the first plate, and has the first thickness. The core material includes one supporting member between the first plate and the second plate and having a second thickness that is greater than the first thickness, wherein each of a surface of the first plate that is perpendicular to a thickness direction of the core material and a surface of the second plate that is perpendicular to the thickness direction has a first area.
