<p>A vacuum insulation material of excellent heat insulation properties which can overcome the limitation of improvement in conventional heat insulation properties, and a device provided with the vacuum insulation material. The vacuum insulation material (1) is provided with envelope materials (200), a core material (100) contained inside the envelope materials (200), and an adsorbing material (400) contained inside the envelope materials (200). The envelope materials (200) comprise heat-welded portions (300) wherein the envelope materials (200) are heat-welded in contact with each other. The heat-welded portions (300) are formed of a material containing hydrocarbon. The adsorbing material (400) adsorbs hydrocarbon gas.</p> |
