Disclosed is a vacuum heat insulating material which contains a fiber produced by spinning a polymer resin having a bending elastic modulus of 3000 MPa or more as a fiber constituting a core material of the vacuum heat insulating material, wherein a polystyrene fiber makes up 80% or more of the fiber. The vacuum heat insulating material has improved recycling properties, can reduce environmental load, and is reduced in cost of materials. L'invention porte sur un matériau d'isolation thermique sous vide qui contient une fibre produite par filage d'une résine polymère ayant un module d'élasticité en flexion de 3 000 MPa ou plus, en tant que fibre constituant un matériau d'âme du matériau d'isolation thermique sous vide, une fibre polystyrène constituant jusqu'à 80 % ou plus de la fibre. Le matériau d'isolation thermique sous vide a des propriétés de recyclage améliorées, peut réduire une charge sur l'environnement et a un coût en matériaux réduit.
