Abstract

A filter element for fluid filtration, in particular for hydraulic fluid, has element components, such as pleated and multi-layer filter material (10) that extends between two end caps (26) and has a fluid-permeable supporting tube (14) forming a hollow cylinder. At least one element component of the filter element is provided at least partially with at least one luminescent material or marker such that the material or marker is excited to a characteristic, detectable wave emission when exposed to a certain exciter wave or wave spectrum.
