    Abstract: The invention relates to a particulate filter for collecting particulate matter from the exhaust gases of an internal combustion engine, having a canal geometry that evolves along the entire length of the canal, such that: —the perimeter of the cross section of the canal decreases continuously from an open end (310) of the canal (370) as far as a reference cross section (350) of the canal, then increases continuously from the reference cross section as far as a closed end (360) of the canal, and —the surface area of the cross section of the canal decreases monotonously from the open end of the canal as far as the closed end. The closed ends are situated in the body of the filter near the outlet and inlet faces respectively for the inlet and outlet canals of the filter.
