Abstract:
There is provided a ceramic filter capable of controlling extraordinary rise of the internal temperature upon regeneration by reducing an amount of deposited soot (particulates) by increasing a passage flow rate in the through-cells and realizing improvement of the regeneration limit and correspondence of PM emission and a method for manufacturing a ceramic filter. A plurality of through channels 7 are formed in the honeycomb segment 2, and the cells are constituted as inlets and/or outlets of the through channels 7 and contain a plurality of honeycomb segments 2 bonded to one another. Each honeycomb segment 2 includes a first inflow port 8, a second inflow port 9, and as a part at least through-cells 10 formed to extend there through in such a manner that fluid can be discharged from the inlet to the outlet of the cells without being plugged at the inlet and the outlet of the cell.
