Abstract
A heat insulating container is described, including an outer glass container and an inner glass container housed therein with a gap formed in-between as a heat insulating layer. A radiant heat preventive film containing a metal oxide is disposed on at least one of the external surface of the inner container or the internal surface of the outer container, wherein the radiant heat preventive film has a reflectivity of 35% or higher with a wavelength of 15 μm. When the thickness of the radiant heat preventive film is 3000 Å, the Hall mobility 'x' (cm/V·s) and the carrier concentration 'y' (cm) of the same satisfy the following formulae: y≧−5×10x+2×10and y≧−6×10x+3×10. When the thickness of the radiant heat preventive film is 5000 Å, x and y satisfy the following formulae: y≧−5×10x+3×10and y≧−6×10x+7×10. Such radiant heat preventive films can have high reflectivity.
