The present invention provides a production method of an anisotropic
conductive film, which method includes the steps of
(a) winding an insulated wire around a core member to form one roll of a
winding layer, this insulated wire including a metal conductor wire and a
coating layer made from an insulating resin, this coating layer being
formed on the wire, placing an insulating resin film on the obtained
winding layer, and repeating the winding and the placing to give a
laminate alternately having the winding layer having a single row of
insulated wires and an insulating resin layer made from the insulating
resin film,
(b) partially or entirely melting at least one of the coating layer and the
insulating resin layer to integrate the winding layer and the insulating
resin layer, and
(c) slicing the laminate along a plane forming an angle with the insulated
wire in a desired film thickness.
