A refrigerator includes a vacuum adiabatic body including a conductive resistance sheet providing a vacuum space part 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 member and a second plate member, wherein at least one of the conductive resistance sheet and each of the first and second plate members are welded to each other to provide a welding part, wherein a plurality of regular beads are provided to a surface of the welding part, and wherein the bead 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. Accordingly, the vacuum adiabatic body is applied, so that it is possible to provide a refrigerator capable of performing a reliable operation and a fabrication method of the refrigerator. |
