Abstract
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 R, and a volume resistivity in the thickness-wise direction in a state pressurised under a pressure of 1 g/mmin the thickness-wise direction is R, the volume resistivity Ris 1×10to 1×10Ω·m, and a ratio (R/R) of the volume resistivity Rto the volume resistivity Ris 1×10to 1×10.
