A sheet 1 for shielding soft X-rays comprises a first outer sheet, an interlayer sheet, and a second outer sheet. In the first outer sheet a port for supplying ionized air is formed. In the interlayer sheet a passage for the ionized air, which passage communicates with the port for supplying the ionized air, is formed. In the second outer sheet a port for discharging the ionized air, which port communicates with the passage for the ionized air, is formed. The sheets 2, 3, and 4 are stacked and adhered so that the sheet 1 has one or more portions 9 for transmitting the ionized air, which portions connect the port for supplying the ionized air, the passage for the ionized air, and the port for discharging the ionized air. |
