FIG. 3 shows an example in which a ventilation hole is formed in a member (102) that can be cut off or attenuated. The conductive material (302) embedded or affixed to the transparent (or translucent) member (301) is made of a net-like material as shown in the figure or a uniform material over the entire surface. This is the calculated interval for the electromagnetic wave that is generated. In addition, the shape of the ventilation hole (303) can be freely selected. However, if the ventilation hole (303) has a mesh shape and is wider than the space between the conductive materials (302),
