A side wall (22) of a filter structure for a particle filter in the exhaust system of an internal combustion engine is produced in that a filter material (38) with a support structure (42) is connected. In particular the method comprises the steps of: A producing (32) a mixture (34) at least from a sintered metal powder (26) and an organic binder (28). b. Establishing (36) a film (38) from the mixture (34); c. Laminating (40) the film (38) on the piece structure (42) and d. sintering (46).
Pollutant extraction is improved thus causing less pollution
