Abstract
Abstract A method of manufacturing an electrically conductive adhesive bond between electrically conductive parts whose surfaces to be bonded exhibit a certain surface roughness, the surfaces to be bonded each being provided with a layer of at least one transition element of the first and/or second transition series of the periodic system of elements, which layer has a surface roughness in the μm-range, such a quantity of an electrically non-conductive adhesive being used to form the adhesive bond that the raised portions of the transition-element-layer are still in contact with each other.
