Description of the invention (7) A coating material having a lambda value not exceeding 0.1, the coating material may not have the function of inhibiting foreign matter from entering the radio wave absorber 2. That is, if the above-mentioned conditions are satisfied, the sheet-like body can be made to deviate from the radio wave absorber 2 to be irradiated into the sheath. The niche 5 is placed side by side and covered, or the covering material may be, for example, a mesh. It is preferable that the radio wave absorbing plate of the present invention has a plate-like body for reinforcement on the inner side of the portion where the radio wave is to be incident. The reinforcing plate system is used to further reinforce the structure I provided with the above-mentioned radio wave absorber and coating material, and is formed of, for example, a plated steel sheet and a galvanized steel sheet, and among them, a stell steel that has both resistance to harsh environments and light weight. The former is better. Number! The figure and the second figure show an example in which a flat plate-shaped reinforcing plate 4 is provided on the other side of the radio wave absorber 2 in the thickness direction. —In the case of realizing a light-weight and constrained radio wave absorber with a larger type (for example, an area larger than lm2), there is a possibility that it may be easily deformed, such as deflection. The flexible radio wave absorber may have poor workability during installation, or may be easily peeled off when subjected to wind pressure. As described above, by further including a plate-shaped field for reinforcement on the incident side of the radio wave, that is, the inner surface side, the radio wave absorber can be reinforced, and an inappropriate deformation of the radio wave absorber can be suppressed. In addition, the plate-like body for reinforcement may be as shown in Fig. 3 and Fig. 4 and Fig. 4, as shown in the figure. For example, in a certain direction along the width direction, the cross-sectional shape of the universal frame has regular irregularities. Square wave board to achieve.

Description of the invention (8) It is better to arrange it approximately perpendicularly to the longitudinal direction of the radio wave absorber 2. 'The radio wave absorber can be reinforced along the length direction that is liable to cause improper deformation, and the rigidity of the radio wave absorption plate in the above direction can be improved. Fortunately, the radio wave absorption plate of the present invention is in the shape of a wave absorber and a plate for reinforcement. There is a reinforcing frame member between the bodies. The reinforcing frame member is, for example, a rectangular member realized by combining a hat-shaped steel plate, and is arranged to intersect at a substantially right angle. The forming method of the reinforcing frame member is not particularly limited. Appropriate number of second widths of reinforcing plate-like bodies arranged along the second width direction Y to the same extent (the examples in Figures 丨 and 2 are three, and the examples in Figures 3 and 4 are two) Between the hat-shaped steel plates, along the first In the direction X, a plurality of cap-shaped steel plates are arranged at appropriate intervals (the examples in FIG. 丨 and FIG. 2 are =, and the examples in FIG. 3 and FIG. 4 are four). The reinforcing frame member, the radio wave absorber 2 is further reinforced in the first-width direction X and the second width direction ya, and even when installed or installed, it will not be deformed improperly such as flexing or bending. Moreover, in the present invention, it is formed The frame member is not limited to the above-mentioned hat-shaped steel plate, and although it is preferably formed by using a conventional L-shaped angle steel plate, door-shaped steel plate, etc., it is more preferable to use a hat-shaped steel plate from the viewpoint of weight reduction. And the covering materials 3, 3, as well as the reinforcing plate-like bodies 4, 4 ', the reinforcing frame member, and the like. The method of fixing between the members of the radio wave absorbing plate of the present invention is not particularly limited. Therefore: Fixing fixtures such as screws and sleeves or conventional adhesives such as epoxy resin, isocyanide, cyanoacrylic acid, hot-melt, rubber, etc. are used for fixing. 0 家 鲜 （CNS ) A4 Secret G G χ 297 Public love) 313171 # Order 529204 A7
