Abstract
A method produces a filter element () having a filter mat () enclosed by at least one fluid-permeable outer envelope (). By an energy input method, at least one part of the filter mat (), which faces toward the outer envelope (), is connected to the outer envelope in at least one connecting zone (). A filter element is produced by this method.
