Claims

[Scope of utility model registration request]

The main direction of small-diameter inorganic fibers 4a is randomly laminated in a direction perpendicular to the heat transfer direction, and organic fibers 4b are sewn into this to form a high-density fiber mat 4, which is arranged in a flat panel. The vacuum heat insulating material is characterized in that the inside is vacuum evacuated, then baked, the organic fibers 4b are incinerated, and after the degassing is completed, the inside is evacuated and sealed.
