The invention provides a honeycomb structure and a method for manufacturing the same. The honeycomb structure (20) has porous partition walls (22), the porous partition walls (22) form a plurality of cells that form fluid flow paths, the average pore diameter of the partition walls (22) is 10 [ mu ] m to 20 [ mu ] m, and the wetted area ratio R (S/V), which is the ratio of the volume V of the partition walls (22) to the wetted area S of the pores, is 0.000239 [ mu ] m ‑1 The above. In the honeycomb structure (20), the porosity of the partition wall (22) may be 50% to 65%. The honeycomb structure (20) can be produced by including 100 parts by mass of a ceramic raw material, a water-absorbing polymer having an average particle diameter after water absorption of 20 [ mu ] m or more and an average particle diameter before water absorption of 2 parts by mass or more, and 0.5 part by mass or more of zirconia in the raw material mixing step. |
