    • PROBLEM TO BE SOLVED: To obtain excellent thermal insulating property and durability by arranging packing bags having thermal insulating material (a) filled into a chamber, and sealing openings of the packing bags in a state of keeping the chamber evacuated to form a vacuum thermal insulating panel. SOLUTION: Packing bags A inserting plate-like thermal insulating materials (a) into them are supplied to a supply section 3 of a manufacturing device 1 in advance by a robot 2, and the packing bags S supplied to the supply section 3 are subsequently conveyed to a mounting section 4 and are mounted on a pallet P. Then, the pallet P mounting the packing bags A in the mounting section 4 is conveyed to a sealing section 15 from a piling up section 7 by a chuck 9, and a chamber cover 17 is turned downward with a hinge section as the center and is stored inside a chamber 18 in an enclosed state. Then, after the inside of the chamber 18 is sufficiently made to reduce pressure, opining sections A' of the packing bags A are welded by heaters to seal, and the sealed and packed packing bags A are covered to a trimming section 31 from a taking out section 30 in a state to mount the packing bags on the pallet P to manufacture the vacuum in succession. Accordingly, wrinkles occurring with the contraction of a packing body can be prevented.
