<P>PROBLEM TO BE SOLVED: To provide a vacuum insulation panel that dissolves an adverse effect caused by installation of an air adsorption material and has a high thermal conductivity reduction effect. <P>SOLUTION: The vacuum insulation panel 1 is configured to vacuum-seal the inside of an outer coating material 6 so that the outer coating material 6 having superior gas barrier properties coats a core material 2 including at least a fiber material, a gas adsorption material 5 that is vacuum-sealed in a bag made of a gas barrier wrapping material 4, and a material 3 having a protrusion that can thirl the wrapping material 4 when an external force is applied. The material 3 is configured so that it deforms and the protrusion thirls the wrapping material 4 to communicate the inside of the wrapping material 4 with the outer coating material 6 when pressed at a side of to the gas adsorption body 5 via the outer coating material 6, wherein the fiber-based core material 2 having superior heat-insulating properties and the gas adsorption material 5 are used, and the wrapping material 4 of the gas adsorption material 5 and the outer coating material 6 of the vacuum heat-insulating material 1 are internally communicated without increasing the number of man-hour so as to maintain superior heat-insulating properties under a low pressure of the fiber-based core material 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
