To provide an electromagnetic wave shielding sheet having excellent shielding performance.SOLUTION: There is provided an electromagnetic wave shielding sheet formed from an emulsified dispersion liquid. The emulsified dispersion liquid contains a dispersion medium, an emulsified dispersion material that is insoluble in the dispersion medium, single-walled carbon nanotubes, and thin film graphite. The emulsified dispersion material is dispersed in the dispersion medium while being surrounded by the thin film graphite, and the single-walled carbon nanotubes are attached to the surface of the thin film graphite.SELECTED DRAWING: Figure 1 【課題】遮蔽性能に優れる電磁波遮蔽シートを提供する。【解決手段】乳化分散液から形成される電磁波遮蔽シートであって、前記乳化分散液は、分散媒と、前記分散媒に非溶解性である乳化分散材料と、単層カーボンナノチューブと、薄膜グラファイトと、を含み、そして、前記乳化分散材料は、前記薄膜グラファイトに囲まれた状態で前記分散媒中に分散し、前記薄膜グラファイトの表面に前記単層カーボンナノチューブが付着している、電磁波遮蔽シート。【選択図】図１
