    • PROBLEM TO BE SOLVED: To solve a problem of a conventional clean room base wrapper, the problem being caused by non-conduction thereof to a steel strut and difficult grounding of current charged on a surface of the steel strut, resulting in stagnation of electric charge on the surface of the steel strut and adverse effect on semiconductor production, etc. SOLUTION: There is provided a new strut base wrapper 1 for the clean room, which consists of a base wrapping frame 2, and base wrapping concrete 5. The base wrapping frame 2 is formed of an electric conductor, and encloses the periphery of a base of the strut 42 in a manner being spaced away from the strut so as to form a space in which concrete is placed. The base wrapping concrete 5 is placed in the space between the base wrapping frame 2 and the strut 42. An inner side of the base wrapping frame 2 is electrically connected to the strut 42 via a conductive rod 4. Further, a surface of the strut, a floor surface, and an upper surface of the base wrapping concrete are subjected to conductive treatment, and the strut surface and the floor surface which have been subjected to the conductive treatment are brought into conduction with each other via the upper surface of the base wrapping concrete which has been subjected to the conductive treatment, and the conductive base wrapping frame.
