However, in the above method, since it is necessary to prepare two types of heat insulating materials, that is, the soft heat insulating material and the compression member, the cost tends to be higher than when one type of heat insulating material is used.
For this reason, it is desired to construct an outer wall heat insulating structure using a normal soft outer heat insulating material. However, when an ordinary soft outer heat insulating material is used, it is difficult to provide the outer heat insulating material on the surface of the outer wall and to fix the exterior material on the surface of the outer heat insulating material. That is, the outer heat insulating material is soft, and there is no guideline for the thickness at the time of construction. Therefore, it is difficult to provide the outer heat insulating material on the outer wall surface with the thickness substantially uniform. Further, since the outer heat insulating material is soft, it is almost impossible to directly fix the exterior material thereon.

The present invention, it is possible to provide the surface of the outer wall of the outer heat insulating material easily and accurately, and to provide a external insulation structure that can be attached to the outer package easily.
