A multi-phase busbar for conducting electric energy includes: a base layer of an insulating material; a first conducting layer of a sheet metal; a first insulating layer of an insulating material arranged on the first conducting layer; a second conducting layer of a sheet metal arranged on the insulating layer; and a second layer of an electrically insulating material which is arranged on the second conducting layer. The first and/or second insulating layers include spacers, each spacer including a layer of a rigid insulating material. At least one of the spacers is glued to an electrically insulating coating of the first and/or second conducting layer, and/or at least one of the spacers is glued to an electrically conductive surface of an uncoated first and/or second conducting layer by an adhesive.
