Abstract

A reception unit is provided including a receiver coil for the contactless transfer of electric energy. The receiver coil includes a plurality of flux guiding elements (16a, 16b) that are made of a highly permeable material and that are designed to concentrate the field lines. The flux guiding elements (16a, 16b) form a continuous molded part that is embodied in a base body (18) and that is combined with the base body to form a component that can be completely prefabricated. The molded part is produced by casting and the base body (18) is used as a casting mold.
