Abstract
A filter element () includes individual components (), such as a filter medium () as one component and further filter element components (), of which at least one component () is made of a material that is at least partially transparent to laser light and at least one further component (), in the manner of a barrier layer, is made of a material that is at least partially opaque to laser light to perform a transmission welding method by laser light for connecting associable components to each other. At least some of the components of the filter element that are exposed to the laser light during the transmission welding method are at least partially electrically conductive.
