Abstract

A filter composed of a filter medium (10) formed from a corrugated filter layer (11) and a flat filter sheet (12) which are interconnected by embossing points (15). This eliminates the need for an additional joining agent. Production of the filter is simplified because no additional materials are required to be supplied or cured.
