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: 1.0354 < Em 3 n a 2 < 188.2097 is satisfied.
