ABSTRACT:
A scale, particularly for a position measuring device, includes a base member and a graduation carrier with a graduation which is fastened with an adhesive layer to the base member. In order to prevent an at least partial separation of the adhesive layer from the contact surface of the base member, the adhesive layer extends in a positively engaging manner with a projection in a dovetail-shaped groove in the contact surface of the base member, so that a secure adhesion of the adhesive layer on the contact surface of the base member is ensured.
