The present invention is directed to an anisotropic conductive film and
manufacturing methods thereof, in which an electrically insulative porous
film made of synthetic resin is used as a base film and in which
conductive parts capable of being provided with conductiveness in the
film thickness direction are formed independently at plural positions of
the base film by adhering conductive metal to resinous parts of porous
structure in such a manner as piercing through from a first surface to a
second surface.
