A honeycomb structure includes at least one honeycomb member including inorganic fibers and having walls extending along a longitudinal direction to define cells. A catalyst is provided on the wall in an amount of at least about 100 g and at most about 400 g per liter of volume of the honeycomb structure. The honeycomb member has a pore distribution measured using mercury porosimetry in which a pore distribution curve has a first peak in a range from about 0.005 &#x3bc;m to about 0.03 &#x3bc;m of a pore diameter, a second peak in a range from about 1 &#x3bc;m to about 15 &#x3bc;m of the pore diameter, and a third peak in a range from about 15 &#x3bc;m to about 50 &#x3bc;m of the pore diameter, where the curve is drawn by plotting the pore diameter (&#x3bc;m) on an X-axis and a log differential pore volume (mL/g) on a Y-axis.

Honeycomb structure, exhaust gas purifying apparatus, and method for producing honeycomb structure

A honeycomb filter includes a pillar-shaped honeycomb structure integrally formed, first and second lamination members, a metal casing containing the honeycomb structure and the lamination member, and first and second end members connected to first and second end portions of the casing, respectively to secure the honeycomb structure and the lamination member. The honeycomb structure includes a wall portion defining through holes which extend substantially along a longitudinal direction of the honeycomb structure, each of the through holes being sealed at either one end portion. Each of the lamination members has aligned through holes extending substantially along the longitudinal direction. The honeycomb structure and lamination members include inorganic fibers oriented substantially perpendicular to the longitudinal direction. The lamination members are provided at first and second end faces of the honeycomb structure, respectively to align the aligned through holes with the through holes of the honeycomb structure.
