<p><P>PROBLEM TO BE SOLVED: To improve heat insulating performance by minimizing an adverse effect due to a heat bridge phenomenon. <P>SOLUTION: In the refrigerator, a vacuum insulation panel 4 comprised by housing a core material 1 comprising glass wool or the like in a bag 3 with high gas shut out performance via an opening and sealing it in vacuum is attached in a box body, and it is filled with a heat insulating material by on-site foaming. The vacuum insulation panel 4 is bent into a U-shape in plan view in accordance with a cross sectional shape of the box body, the vacuum insulation panel 4 is adhered to a back face and heat insulating material forming face sides of both side faces of an inner box 12 forming the box body, an urethane heat insulating material 20 is filled therein and foamed, and a heat insulating material 13 is formed by the urethane heat insulating material 20 and the vacuum heat insulating panel 4. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
