A printed circuit board and a method for producing a printed circuit board consisting of at least two printed circuit board regions, wherein the printed circuit board regions each comprise at least one conductive layer and/or at least one conductive component, wherein printed circuit board regions to be connected to one another, in the region of in each case at least one lateral surface directly adjoining one another, are connected to one another by a mechanical coupling. At least one sub-region or connection port of the conductive layer, and/or a conductive element of the component are electrically conductively coupled to each other at the lateral surface.
