The elastic anisotropically conductive films each have a plurality of conductive parts for connection extending in a thickness-wise direction thereof and containing conductive particles, and an insulating part mutually insulating them. The conductive particles are obtained by coating core particles exhibiting magnetism with a high-conductive metal, a proportion of the high-conductive metal to the core particles is at least 15 % by mass, and the following t is at least 50 nm: t = Ä1/(Sw. rho )Ü x ÄN/(1 - N)Ü, wherein Sw is a BET specific surface area (m /kg) of the core particles, rho is a specific gravity (kg/m ) of the high-conductive metal, and N is (mass of the high-conductive metal/total mass of the conductive particles).

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.
