A thermally-insulated double-walled container is disclosed made of synthetic resin which is formed by joining together an inner container and an outer container in a unitary fashion to form a space therebetween; wherein a thermoinsulating layer is formed in the space between the inner container and the outer container by filling the space with at least one low thermoconductive gas selected from the group consisting of xenon, krypton, and argon; and wherein the inner container and the outer container are multilayer molded from different synthetic resin materials. The container provides an excellent gas-barrier capacity without requiring plating of the outer surface of the inner container or the inner surface of the outer container in the double walled container and maintains its mechanical strength over a long period of time and having an excellent thermoinsulating capacity. The container is suitable as a thermos, cooler box, ice cooler, thermoinsulated cup, insulated lunch box, or the like.
