Beschreibung
Zusammenfassung:	A honeycomb structure comprising a pillar-shaped honeycomb structure body having a porous partition wall disposed so as to surround a plurality of cells, whereinlet that A denotes an absolute value of open frontal area (%) in a plane of the honeycomb structure body orthogonal to the extending direction of the cells and P denotes an absolute value of porosity (%) of the partition wall, the honeycomb structure has a value represented by the following expression (1) that is 0.05 to 0.12,let that D denotes an average pore diameter (m) of the partition wall and G denotes a geometric surface area (mm2/mm3) of the partition wall, the honeycomb structure has a value represented by the following expression (2) that is 8 to 50 (μm×mm2/mm3), andthe honeycomb structure has a hydraulic diameter of the cells that is 1.1 mm or more,(1−A/100)×(1−P/100), Expression (1)D×G. Expression (2)
