[0013] 1k per electromagnetic shield clothing in this example
The electromagnetic shielding effect was measured in the wavelength band of Hz to 1 THz, and a dB value of 50 dB was obtained, revealing a large electromagnetic shielding effect. Measurement was performed using the Advantest method. That is, a sample was installed between a transmitting probe antenna and a receiving probe antenna in a shield box, and the attenuation rate (dB) was determined from the intensity ratio of the transmitted electromagnetic wave and the received electromagnetic wave. Measurement frequency is 1kHz to 1TH
Measurements were made by continuously changing z. The above-mentioned attenuation factor (
dB) values are 1kHz, 1MHz, 1GHz and 1TH
This is the average value of the attenuation rate (dB) at four points of z.

[0014] Temperature and humidity tests were also conducted at 80°C and at a relative humidity of 95% for 100 hours.
There was no change at 0 dB.

[0015] After carrying out a washing test by separating the clothing part 12 from the shielding member 1 and washing it 20 times in a household washing machine, the attenuation rate (dB) was measured and the dB value was 50 dB, with no change. .

According to this embodiment, the clothing section 12 includes the storage section 6 in which the shield member 1, the outer fabric 2, and the inner fabric 3 are sewn together.
