<p><P>PROBLEM TO BE SOLVED: To provide a vacuum heat insulating material capable of easily determining a construction material of a core material, when recycling the vacuum heat insulating material. <P>SOLUTION: This vacuum heat insulating material 50 includes the core material 51 composed of a fiber assembly, an inner bag material 53 for storing the core material 51 and an outer bag material 54 for storing the inner bag material 53, and information on the construction material of the core material 51 is displayed on a surface of the outer bag material 54. Information of indicating a construction material name of the core material is displayed as the information on the construction material of the core material, and the heat resistant temperature of the core material is displayed. A recess-projection is arranged in the fiber assembly of the core material 51, and the information on the construction material of the core material is displayed on an outer bag material surface by sealing the inside of the outer bag material 54 by reducing pressure. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
