ELECTROMAGNETIC WAVE ABSORPTION BOARD TO BE USED IN WIRELESS LAN

摘要

An electromagnetic wave absorption board to be used for a wireless LAN is provided with a double glass wherein a pair of transparent glass sheets are arranged at an interval by having a spacer at the circumference end portion, and a hollow layer sealed between the glass sheets is formed. The thickness of the glass sheet is within a range of 2.5-20mm, the thickness of the hollow layer is within a range of 2.5-15mm, and a resistive film having a surface resistance within a range of 20-2KO/sq is formed at least on one glass sheet of the pair of glass sheets, and the resistive film is formed on the glass sheet surface on the hollow layer side.
