Abstract
A process for preparing an electrical connecting member having a holding member comprising an electrically insulating material and 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 each holding member, the process having the following steps, namely the step of forming a matrix having the state where the holding member is in contact with a base member for supporting the holding member the step of irradiating a high energy beam on the matrix from the holding member side to remove the holding member, thereby forming a plurality of holes the step of filling an electroconductive material which becomes the electroconductive member into the plurality of holes formed and the step of removing the base member.
