A heat insulating container and its manufacturing method is provided. The heat insulating container comprises an inner container and an outer glass container, in which the breakage of the glass containers can be prevented even if a minute flaw is formed on either of the glass containers. The insulating container possesses a superior radiant heat insulating capability. The inner glass container is housed in the outer glass container with a gap in between, which air-gap functions as a heat insulating layer. A radiant heat preventive film containing metal oxide is provided at least either on the outer surface of the inner glass container or on the inner surface of the outer glass container with an intermediate film containing SiO2 in between.
A heat insulating container having an inner glass container housed in an outer glass container with a gap formed in-between, said gap constituting a heat insulating layer, wherein a radiant heat preventive film containing metal oxide is formed on at least either of an outer surface of the inner glass container or an inner surface of the outer glass container with an intermediate film containing SiO2 disposed in between the outer surface of the inner glass container and the radiant heat preventive film or in between the inner surface of the outer glass container and the radiant heat preventive film.
