According to the invention, said drainage element (2) is made of a non-woven filtering material which is arranged in a laminated manner between the filter membranes (3) respectively by means of an adhesive non-woven material (4). The invention also relates to a method for producing a filter element (1), a drainage element (2) made from a non-woven filtering material being laminated between two filter membranes (3). An adhesive non-woven material (4) is arranged between the drainage element (2) and each filter membrane (3), then lamination takes place due to the thermal effect under pressure.
