A telescopic electric conductor includes an electrically conductive first tube having a longitudinal axis and an electrically conductive second tube movable relative to the first tube along the longitudinal axis while being at least partly received within the first tube. An electrically conductive flexible self-supporting element is arranged inside the first tube and is mechanically and electrically connected to the first tube and to the second tube. The flexible element is arranged to elastically deform along the longitudinal axis. The flexible element has a waveform shape with several cycles of the waveform includes a number of sections that are welded together, each section having a shape of a half cycle of the waveform.
