<p>Disclosed is a honeycomb structure which controls thermal damage when the honeycomb structure is regenerated by heating, and which is not susceptible to the production of micro-particulate embers collected on partition walls, even at the outer circumference. Further disclosed are a filter and an exhaust gas treatment device using the same. Disclosed is a honeycomb structure, in which honeycomb structure, the partition walls are made from a porous material in which the average pore size is not less than 5 µm and not greater than 28 µm, and a half width with respect to the average pore size on a pore distribution curve is 25 µm or less (not including 0 µm). Since mechanical strength is maintained, increases in pressure loss are suppressed, and there is little variation in pore size, heat is easily transmitted from the center of the honeycomb structure to the outer circumference thereof, whereby thermal damage can be suppressed and burning off of microparticles collected on the partition walls can be quickly advanced.</p> |
