Abstract
A filter element comprising a pleated filter mat (3), the terminal axial ends (7, 8) of which are connected by an end cap (9, 11) and which includes a main structural layer (15) having filtering properties and at least one first additional structural layer and a second additional structural layer (17, 19), the surface area of each of said additional structural layer (17, 19) being smaller than the surface area of the main structural layer (15), is characterized in that the axial ends (12, 14) of one additional structural layer (17) is located at n an axial distance from the axial ends (16, 18) of the other additional structural layer (19) on the filter mat (3).
