ばアルミテープ等のシール材１１にて密封する。Reference numeral 7 denotes a heat insulator, and the space formed by the outer plate 2 and inner plate 3 is filled with a foam body 8 such as an open-cell foam. At this time, bubble breakage occurs at the contact surfaces between the foam body 8, the outer plate 2, the inner plate 3, and the air due to wall resistance and heat radiation, and a skin 9 is formed. The foam body 8 has air permeability, but the skin 9 is a resin layer and has significantly reduced air permeability. Therefore, an opening 10 is provided in a part of the outer panel 2 or the inner panel 3 so that the foam body 8 overflows the outer panel 2 or the inner panel 3, and the foam body 8 is formed along the surface of the outer panel 2 or the inner panel 3. The overflowing part is removed with a cutter or the like, and the pressure inside the part is reduced from that part, and when the pressure reaches a predetermined level, it is sealed with a sealing material 11 such as aluminum tape.
