Description of the Related Art Conventionally, there has been known a vacuum heat insulating panel in which an inorganic fine powder such as silica or calcium silicate is used as a heat insulating base material and this is enclosed in a bag made of a gas barrier film in a reduced pressure state. Since this fine powder-filled type vacuum heat insulating panel uses fine powder as a heat insulating base material, its end portion has a bad rule of shape and dust is not generated sufficiently when it is discarded. Further, as an improved one of the drawbacks of the fine powder-filled type vacuum heat insulating panel, there is known a molded body-enclosed vacuum heat insulating panel using a foamed polyurethane molded body, a calcium silicate molded body or the like as a heat insulating base material.
