The object of the invention is to provide heat insulating wall structure which is simple and in which the execution of works is easy, a cold (thermal) bridge is prevented by reducing heat conduction to a metal framework and the rust of the framework and internal dew condensation can be prevented. To achieve the object, a bearing plywood 2 is fastened to the outside of the metal frame 1, a furring strip 5 is fastened to the outside of the bearing plywood 2, an exterior finishing board 8 is fastened to the outside of the furring strip 5, and foamed heat insulating material 20 is inserted between the frame 1 and bearing plywood 2 or between the bearing plywood 2 and the furring strip 5. The foamed heat insulating material 20 is formed by mixing bearing members 30 made of rubber or plastic in a foamed body provided with a continuous foamed layer 21, highly foamed parts 22 arranged in plurality at least on one side of the continuous foamed layer and made of thermoplastic resin and lowly foamed thin parts 23 that covers the outer surface of the highly foamed parts together with the continuous foamed layer. <IMAGE>
