Abstract: Provided is a vacuum adiabatic body. The vacuum adiabatic body includes a supporting unit configured to maintain a vacuum space part. The supporting unit includes a plurality of bars extending in a vertical direction between the first plate member and the second plate member. When a pitch of the bar is a, an elastic modulus of a material forming the bar is E, and a radius of a long axis is n and a radius of a short axis is m when a cross-section of the bar has an elliptical shape is n, the following equation:

Abstract: A vacuum adiabatic body includes a first plate configured to define at least a portion of a wall for a first space, a second plate configured to define at least a portion of a wall for a second space having a temperature different from that of the first space, and a support configured to maintain the third space. The support includes a coupling mechanism by which a first support plate and a second support plate are coupled to each other and integrated with each other and a seating mechanism configured to maintain a gap between the first support plate and the second support plate at points at which the first support plate and the second support plate contact each other. The seating mechanisms are spaced apart from the coupling mechanism.

Abstract: A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body may include a sheet base provided in a direction crossing a vacuum space between a first plate and a second plate, and at least one sheet protrusion that protrudes from the sheet base in at direction toward one of the first plate or the second plate to maintain an interval between the sheet base and the one of the first plate or the second plate.
