자계/전계, 양쪽의 노이즈에 대하여, 높은 노이즈 흡수 효과를 발휘하며, 또한, 그 노이즈 흡수 효과가 보다 광대역에 유효한 노이즈 흡수 시트를 제공하는 것. 적어도 2종의 층이 적층된 노이즈 흡수 시트로서, 자성 재료를 함유하는 자성체층과, 구성 섬유에 금속이 부착되어 있는 노이즈 흡수 포백의 층이 적층되어 있고, 상기 노이즈 흡수 포백의 적어도 한쪽면의 표면 저항률의 상용 로그값이 0∼6의 범위에 있는 것을 특징으로 하는 노이즈 흡수 시트. Provided is a noise-absorbing sheet that is highly effective at absorbing noise from magnetic and/or electric fields, the noise-absorbing effect being effective in wider bandwidths. A noise-absorbing sheet upon which at least two layers are stacked, wherein the noise absorbing sheet is characterized in that a magnetic layer containing a magnetic material and a layer of a noise-absorbing fabric in which a metal is deposited on constituent fibers are layered on said sheet, and the common logarithmic value of the surface resistivity of at least one side of the noise-absorbing fabric is 0 to 6.
