A honeycomb body having intersecting porous walls including first to fourth cells, the cells extending from an inlet face to an outlet face, defining a repeating structural unit having three inlets and one outlet channel. Plugged to form. The repeating structural unit includes a first channel having a length L 1 , a width W 2 , and an area A 1 , a second channel having a length L 2 , a width W 2 , and an area A 2 , and a length L 1 , a third channel having a width W 1 , and an area A 3, and a fourth channel having a length L 2 , a width W 1 , and A 4 , wherein the first to third channels are at an inlet. Yes, the fourth channel is a rectangular outlet, and is at least one of W 1 ≧ W 2 , and L 1 ＷL 2 (ie, W 1 ≧ W 2 , or L 1 か L 2 ) Or W 1 ≧ W 2 and L 1 ≠ L 2 . The repeating structural unit has a quadrilateral perimeter. A particulate filter, a honeycomb extrusion die, and a method for manufacturing a honeycomb body including the honeycomb body are provided. |
