Abstract
A method of producing an electrical connection member includes the steps of applying a carrier containing a light-sensitive resin onto a substrate member, forming holes in portions of the carrier to form a pattern and expose the substrate member in the holes, filling each hole in the carrier with an electrically conductive member, and removing the substrate member from the carrier. With this method, it is possible to easily produce electrical connection members in which high density electrical connecting portions can be provided and in which the reliability and security of electrical connections can be improved.
