HEAT INSULATION MATERIAL, HEAT INSULATION MATERIAL MODULE, AND COMBINATION OF ARTICLE AND HEAT INSULATION MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a heat insulation material that easily and simply discharges static electricity outward when the static electricity is built up within a covering material for the internally-decompressed heat insulation material, and a heat insulation material module.SOLUTION: A heat insulation material 10 comprises a core material 12, and a bag-like covering material 11 that houses the core material 12 and that is internally decompressed. Outer surfaces of the covering materials 11 of the respective heat insulation materials 10 are brought into a mutual conduction state so that static electricity built up in the covering material for the internally-decompressed heat insulation material can be easily and simply discharged outward.
