An air spring comprising a rolling piston, a bellows with a rolling fold which can be rolled on the wall of the rolling piston, and at least one flat sensor element that can be actuated by the rolling movement of the bellows, and that generates a height-dependent signal. The sensor element is integrated into the wall of the rolling piston or is disposed on the side of the wall that faces the hollow space of the rolling piston.
