VACUUM HEAT INSULATING BODY, MANUFACTURING METHOD OF VACUUM HEAT INSULATING BODY AND HEAT RESERVING VESSEL

摘要

PROBLEM TO BE SOLVED: To obtain a vacuum heat insulating body which has sufficient heat insulating performance by preventing thinning of the vacuum heat insulating body and avoiding a member which forms a projection. SOLUTION: This portions 4a, 4b are partially formed on a vacuum heat insulating body 1 composed of a porous core member 2 and an outer coating member 3. The thin portions are arranged on portions forming projections on the heat insulated surface, so that the thinning of the vacuum heat insulating body is dispensed with.
