Abstract

A filter element (10) of a filter for fluid, in particular fuel, oil, water, urea solution or air, in particular of an internal combustion engine, in particular of a motor vehicle, and a method for producing the same are described. The filter element (10) comprises a filter medium (14), which is designed as a filter medium hollow body (12) and is circumferentially closed at least with respect to an imaginary axis (16). On at least one end face, the filter medium (14) comprises an end body (20). The end body (20) comprises a closing section (28), which is sealingly connected at least to the filter medium (14). Moreover, the end body (20) has a central fluid opening (24) into which a tube-like connecting element (38) of the filter can be inserted. At least one sealing section (30) is provided on the end body (20) for circumferentially sealing the fluid opening (24) with respect to the tube-like connecting element (38). The at least one sealing section (30) is integrally connected to the closing section (28) by way of at least one flexible joining section (32).
