Abstract

The present invention relates to a honeycomb structured body including a honeycomb fired body in which multiple through-holes are arranged longitudinally in parallel with one another with a partition wall therebetween, wherein the honeycomb fired body is an extrudate containing ceria-zirconia composite oxide particles and alumina particles, and when the pore size of the partition wall of the honeycomb fired body is measured by mercury porosimetry, and the measurement results are shown as a pore size distribution curve with pore size (μm) on the horizontal axis and log differential pore volume (ml) on the vertical axis, at least one peak is present in each of the pore size ranges of 0.01 to 0.1 μm and 0.1 to 5 μm.
