Zusammenfassung:To provide a noise suppression sheet with high shielding effect.SOLUTION: A noise suppression sheet 1 includes a first magnetic layer 10. The first magnetic layer 10 includes a plurality of first regions 11 stacked in a thickness direction, and a second region 12 located between the first regions 11. The first magnetic layer 10 includes a first metal component made of Ni, a second metal component made of Fe, and a third metal component other than Ni and Fe, and the concentration of the third metal component in the second region 12 is higher than the concentration of the third metal component in the first region 11.SELECTED DRAWING: Figure 2 【課題】シールド効果の高いノイズ抑制シートを提供する。【解決手段】ノイズ抑制シート１は、第１磁性層１０を備える。第１磁性層１０は、厚み方向に積層された複数の第１領域１１と、第１領域１１間に位置する第２領域１２を含む。第１磁性層１０は、Ｎｉからなる第１金属成分と、Ｆｅからなる第２金属成分と、Ｎｉ及びＦｅ以外の第３金属成分を含み、第２領域１２における第３金属成分の濃度は、第１領域１１における第３金属成分の濃度より高い。【選択図】図２
