Abstract
A capacitive distance sensor is provided. The distance sensor includes a sensor element having an electrically conductive, elongated, flat sensor area which in turn contains a number of holes. The sensor area is completely surrounded by an electrically non-conductive insulating body, with the result that the insulating body completely covers the edge regions of the holes. The sensor element is produced, in particular, by first of all making the holes in the sensor area. In a subsequent step, the sensor area is completely encased by the insulating body which also completely fills the holes in the sensor area.
