Document Type and Number:
WIPO Patent Application WO/2020/115808
Kind Code:
A1
Abstract:
Provided is a heat insulating material which can prevent ingress of gas at low cost. The present invention comprises: a core material 3; first packing materials 5a, 5b which cover the core material 3, have a reduced internal pressure, and comprise a polymeric compound; and particles 7 which engage with gas-permeable gas permeation pathways 21a, 21b of the first packing materials 5a, 5b from outside the first packing materials 5a, 5b due to the difference in pressure between the inside and outside of the first packing materials 5a, 5b to prevent permeation of gas.
