Abstract:
A refrigerator includes a vacuum adiabatic body including a conductive resistance sheet providing a vacuum space that has a temperature between a temperature of an internal space and a temperature of an external space and is in a vacuum state, the conductive resistance sheet capable of resisting heat conduction between a first plate and a second plate, wherein at least one of the conductive resistance sheet and each of the first and second plates are welded to each other to create a welding part, wherein a plurality of regular beads are provided to a surface of the welding part, and wherein the plurality of regular beads includes: a parabolic inflection region provided at a center portion; linear regions respectively provided at both outsides of the inflection region; and edge regions respectively provided at outsides of the linear regions.
