Abstract

An anisotropically conductive member includes an insulating base having through micropores and conductive paths formed by filling the through micropores with a conductive material, insulated from one another, and extending through the insulating base in its thickness direction, one end of each of the conductive paths exposed on one side of the insulating base, the other end of each of the conductive paths exposed on the other side thereof. The insulating base is an anodized film obtained from an aluminum substrate and the aluminum substrate contains intermetallic compounds with an average circle equivalent diameter of up to 2 µm at a density of up to 100 pcs/mm 2 . The anisotropically conductive member dramatically increases the density of disposed conductive paths and suppresses the formation of regions having no conductive paths, and can be used as an electrically connecting member or inspection connector for electronic components.
