Beschreibung
Zusammenfassung:	A vacuum heat insulator according to the present disclosure includes a core material and an outer packaging material including an inner plate and an outer plate each of which includes a resin sheet. The core material is covered by the outer packaging material. The vacuum heat insulator further includes a heat welded part formed by welding a part of the inner plate and a part of the outer plate. The heat welded part has a recess having a thickness that is 50% or less of an average thickness of the heat welded part. As a result thereof, the adhesion and airtightness of the heat welded part can be maintained, and a highly reliable vacuum heat insulator can be provided.
