To provide a vacuum heat insulating material capable of reducing time required for production by shortening time required for evacuation.

This vacuum heat insulating material is formed by evacuating the inside of a plastic film 31 after using non-woven fabrics 21 of layered plastic as a core material 2 and sealing it with a plastic film 31, so as to integrate the core material 2 with the plastic film 31. The non-woven fabrics 21 are layered so that distribution directions of fibers forming the non-woven fabrics 21 may cross alternately one by one.
