There is disclosed a set of current collecting elements used for a current collecting roller which feeds current to a transportation apparatus. The set of current collecting elements comprises a plurality of electroconductive elements arranged in juxtaposed relation to one another, said electroconductive elements being tightly and rigidly secured to each other by a lead wire at the lower portion of said elements. The current collecting roller using the present sets of current collecting elements is protected from being damaged by heat being generated between current collecting member and each of the electroconductive elements.
