The present invention relates to a diesel particle filter comprising a ceramic wall flow filter substrate and a coating of a high-melting material applied in the infeed channels. The coating (6) is made such that it closes off the pores (5) connecting the inflow channels (1) and outflow channels (2) in the wall (4) on the inflow side for soot particles (7), without thereby preventing the penetration of gaseous exhaust gas components. The coating can be produced from one or more high-melting point oxides or from high-melting point fiber material. In both cases, the coating leads to a significant reduction in deep filtration, and thus the back pressure increase that can be observed during deep filtration is significantly lowered.
