摘要： PROBLEM TO BE SOLVED: To develop an electromagnetic wave absorption panel that can prevent degrading of absorption performance in case when the incident angle of an electromagnetic wave becomes large, and to improve its sound absorption performance so as to use it separately as a sound-insulating wall.
SOLUTION: A foaming glass panel containing a conductive fiber is arranged in a panel-like box so that its surface becomes corrugate. When an electromagnetic wave enters from the right side, a panel face directing mainly in the right direction absorbs it, and when it enters from the left side, a panel face directing mainly in the left direction absorbs it. Therefore, when the electromagnetic wave enters at a large incident angle, the electromagnetic wave absorption performance of the entire panel can be improved. A number of small holes are formed in a foaming glass, or a sound insulating material is provided on the front and rear surfaces of the foaming glass panel, thereby improving its sound insulating performance.

For the light reflecting layer 5, a material for passing the radio wave, for example, a Scotch light reflecting sheet (R) 6060 white made by the Sumitomo 3 M company is used. A material of the dielectric layer 2 is composed of a composition of blending, for example, conductive titanium oxide (FT-2000 made by the Ishihara Industry Co., Ltd.) and/or conductive carbon black (a commodity name (Ketjen Black) made by the Japan EC Co., Ltd.) with a base material. For the base material, a thermosetting resin (properly selected from, for example, an epoxy resin, polyurethane resin, a polyester resin, and a phenol resin) is used.
