PROBLEM TO BE SOLVED: To facilitate transportation and storage, by extending in a simplified structure, a resistance film and a reflecting film, while keeping the predetermined interval between these elements so that wrinkles are not generated. SOLUTION: A first upper frame 1a is adhered to the upper end edge of the resistive film A; a first lower frame 2a is adhered to a lower end edge of the resistance film A; and a first vertical frame 3a with the upper and lower ends abutting against or coupling with each end of the first upper frame 1a and the first lower frame 2a is mounted to both the right and the left end edges of the resistive film A, with elastic deformation, curved internally in the shape of an arc. The side of the reflecting film B is also mounted to the right- and to the left-end edges of the resistance film B. While the resistive film A and the reflecting film B are held in parallel with an interval-holding member 4 with the predetermined interval d kept between these elements; the first upper frame 1a, a second upper frame 1b, the first lower frame 2a, and a second lower frame 2b are mounted to a support base frame 5. In addition, an elastic spring energizing means 6 for the vertical direction is provided for elastically energizing the first upper frame 1a, second upper frame 1b, first lower frame 2a, and second lower frame 2b in a direction of relatively separating from each other.
