Abstract

A process for preparing an electrical connecting member having a holding member comprises an electrically insulating material, a plurality of electroconductive members equipped in the holding member under the state mutually insulated from each other, one end of the each electroconductive member being exposed at one surface of the holding member, and the other end of the each electroconductive member being exposed at the other surface of the holding member, the process comprising the steps of: (A) constituting a matrix member by providing a photosensitive resin which becomes the holding member on both surfaces of a base member, respectively; (B) exposing and developing the respective photosensitive resins to form a plurality of holes through the photosensitive resins, thereby having the base member exposed; (C) curing the photosensitive resins; (D) etching away a part of the base member exposed; (E) filling an electroconductive member into the holes formed in the holding members coplanar with or protruded from the holding members; and (F) removing the base member which remains.
