Abstract
The present invention provides a honeycomb structured body containing a ceria-zirconia composite oxide and being less susceptible to ring-off cracking. The honeycomb structured body of the present invention includes 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 contains ceria-zirconia composite oxide particles and inorganic fibers, and a b-axis thermal expansion coefficient measured in a direction along a b-axis representing a direction perpendicular to a longitudinal direction of the honeycomb structured body is higher than an a-axis thermal expansion coefficient measured in a direction along an a-axis representing the longitudinal direction of the honeycomb structured body.
