Abstract
An electrical resistance component comprises an electrically insulating carrier, at least one resistance layer on the carrier, and at least one electrical connector formed at the carrier and connected to the resistance layer, wherein the resistance layer has a surface structure along its surface at a side facing away from the carrier. The resistance layer is further covered by a barrier layer that comprises an inorganic material and that reproduces the surface structure of the resistance layer continuously and with a uniform thickness.
