PROBLEM TO BE SOLVED: To provide a wall structure excellent in size stability or sound insulation performance which can be obtained by making use of simple reuse of construction waste materials made of inorganic materials. SOLUTION: Construction waste materials 14 composed of inorganic materials generated at the time of demolishment, reformation or construction of a building are processed by a simple processing such as cutting especially without classification only by attaching to the inside face of a face member 12a, a wall structure A excellent in size stability or sound insulation performance can be obtained. Further, as the construction waste materials 14 are attached to only one inside face of face materials 12a, 12b forming a double wall, even if a sound wave with a specified frequency permeates one side face material by coincidence effect, since the sound wave is insulated by the other face material, the sound insulation performance can be improved as the whole body of the wall structure A.
