Abstract

One aspect relates to a soot sensor for detecting electrically conductive and/or polarizable particles, including a substrate, an electrode layer that is formed on the substrate and that includes at least two spatially separated electrodes that engage into each other. At least one cover layer is formed on the side of the electrode layer facing away from the substrate. Multiple openings are formed in the cover layer, the openings at least partially exposing a surface of one electrode of the at least two electrodes.
