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 R0, and a volume resistivity in the thickness-wise direction in a state pressurised under a pressure of 1 g/mm2in the thickness-wise direction is R1, the volume resistivity R1is 1×107to 1×1012Ω·m, and a ratio (R0/R1) of the volume resistivity R0to the volume resistivity R1is 1×101to 1×104.
