PROBLEM TO BE SOLVED: To provide anisotropic conductive film which has elasticity in the film thickness direction, in which conduction in the film thickness direction with a low compressive load is possible, furthermore in which elasticity recovery is possible, and which is suitable for frequent uses. SOLUTION: This anisotropic conductive film is characterized in that an electrically insulating porous film formed of a synthetic resin is used as a base film; conductive parts formed of a conductive metal adhering to the resin part of a porous structure on wall surfaces of through holes penetrating from a first surface to a second surface and formed by a process of forming the through holes in the film thickness direction of the porous film, and capable of giving conductivity only in the film thickness direction are respectively arranged independently in a plurality of parts of the base film; and the respective conductive parts are formed of the conductive metal adhering to the resin part of the porous structure on the wall surfaces of the respective through holes with the porous structure of the porous film held thereto. Its manufacturing method is also provided. COPYRIGHT: (C)2008,JPO&INPIT
