Disclosed herein is an anisotropically conductive sheet capable of holding charge in its surfaces under an unpressurised state, and moving the charge held in the surface in a thickness-wise direction thereof in a state pressurised in the thickness-wise direction, thereby controlling the quantity of the charge at the surface. This anisotropically conductive sheet comprises a sheet base composed of an elastomer and conductive particles exhibiting magnetism contained in the sheet base in a state oriented so as to arrange in rows in a thickness-wise direction of the sheet base, and dispersed in a plane direction thereof. Supposing that a volume resistivity in the thickness-wise direction under an unpressurised state is R0, and a volume resistivity in the thickness-wise direction in a state pressurised under a pressure of 1 g/mm<2> in the thickness-wise direction is R1, the volume resistivity R1 is 1 x 10<7> to 1 x 10<12> OMEGA .m, and a ratio (R0/R1) of the volume resistivity R0 to the volume resistivity R1 is 1 x 10<1> to 1 x 10<4>. <IMAGE> |
