Patent ID: 8524607

Claim:
A method of manufacturing an anisotropically conductive member comprising: an insulating base material; and conductive paths composed of a conductive material which pass in a mutually insulated state through the insulating base material in a thickness direction thereof and which are provided in such a way that a first end of each conductive path is exposed on a first side of the insulating base material and a second end of each conductive path is exposed on a second side of the insulating base material; wherein the conductive paths have a density of at least 2 million paths/mm 2 and the insulating base material is a structure composed of an anodized aluminum film having micropores therein, the method comprising, in order: an anodizing step of anodizing an aluminum substrate so as to form the anodized film having micropores therein; a perforating step of passing holes determined by the micropores through the anodized film so as to obtain the insulating base material; and a metal filling step of filling a metal as the conductive material into the holes which pass through the insulating base material so as to obtain said anisotropically conductive member.
