Abstract
A scale element for an inductive position measuring device includes a substrate on which a graduation track is arranged. The graduation track is formed along a measuring direction from a periodic sequence of alternately arranged electrically conductive graduation regions and non-conductive graduation regions. The electrically conductive graduation regions are formed from a layer of electrically conductive material. At least one bore is arranged in the substrate for fastening the scale element to a machine part. The electrically conductive graduation regions have an opening, in which the electrically conductive material encloses the opening. In at least one of the electrically conductive graduation regions, the bore is arranged in the substrate through the opening.
