Abstract: The present invention relates to a honeycomb structure having promoter particles and a binder phase interposed between the promoter particles, and a method for manufacturing the same. The promoter particles contain at least first promoter particles made of a ceria-zirconia solid solution. The binder phase, in each of which a number of inorganic binder particles are aggregated with each other, with α-alumina being a main component, contain one or two of Fe and Cr dissolved in α-alumina. The honeycomb structure has a specific surface area at a ratio of 90% or more of after heating to before heating at a temperature of 1200° C.
