Honeycomb structure

A honeycomb structure includes a porous partition wall disposed so as to surround cells extending from a first end face to a second end face. The cells include partially clogged cells which account for 10 to 80% of the total number of the cells, and each of which includes a protrusion that protrudes...

Beschreibung
Zusammenfassung:	A honeycomb structure includes a porous partition wall disposed so as to surround cells extending from a first end face to a second end face. The cells include partially clogged cells which account for 10 to 80% of the total number of the cells, and each of which includes a protrusion that protrudes inward from the surface of the partition wall. The protrusion is partially formed in a direction in which each partially clogged cell extends. In a projected view from the first end face to the second end face, a ratio of area of the protrusion in each partially clogged cell to whole area of the through channel of each partially clogged cell is 5 to 80%, the whole area including the protrusion, and the partition wall surrounding each partially clogged cell has a thickness at a thinnest part of 0.038 mm or more.
