Abstract
An angle detection device, in particular for a fuel filling level detection device includes: a carrier; a cover, which has been connected to the carrier by at least one solder or adhesive connection layer; and a sensor for the contactless detection of an orientation of a magnetic field of a magnet. The sensor has been arranged in an interior space, which has been defined by the carrier and the cover, in particular on the carrier.
