Proposed is a diesel particle filter which comprises a ceramic wall-flow filter substrate and a coating applied in the inflow ducts, which coating is composed of material with a high melting point. The coating (6) is provided such that, by means of said coating, pores (5), which connect the inflow ducts (1) and outflow ducts (2), in the wall (4) are closed off for the soot particles (7) at the inflow side without said coating thereby preventing the passage of the gaseous exhaust-gas constituents. The coating may be produced from one or more oxides with a high melting point or from fibrous material with a high melting point. In both cases, the coating has the effect that the depth filtration is considerably reduced, and therefore the back pressure increase encountered during the depth filtration phase is significantly reduced.
