Beschreibung
Zusammenfassung:	A vacuum heat insulating material includes a sheath material and a core material that is sealed inside the sheath material in a hermetically sealed decompressed state. The sheath material comprises a gas barrier layer and heat sealing layer (22A). Heat sealing layer (22A) contains a heat sealing resin and filler (41) with an aspect ratio exceeding 1. In heat sealing layer (22A), at least some of filler (41) is oriented, with a long-axis direction intersecting with a direction in which heat sealing layer (22A) spreads. Accordingly, there is provided a vacuum heat insulating material capable of preventing entry of a gas to the inside and favorably ensuring the hermetically sealed decompressed state on the inside.
