Abstract: This busbar (1) includes at least two conductive elements (10, 16, 20, 26, 30, 36, 40) which include electrical connection elements (14, 24, 34, 18, 28, 38, 44) of windings belonging to the stator of an electric machine. All of the conductive elements (10, 16, 20, 26, 30, 36, 40) are each cut out from a plate of electrically conduction material, bent according to a direction perpendicular to the thickness of the plate and radially superimposed in relation to a central axis (Y-Y) that is common to the conductive elements (10, 16, 20, 26, 30, 36, 40).
