A honeycomb structure includes at least one a honeycomb unit having a longitudinal direction. The at least one honeycomb unit includes a SOx occluding agent, inorganic particles, an inorganic binder, and partition walls extending along the longitudinal direction to define plural through-holes. A relationship 5X+30≦̸Y≦̸5X+45 (about 1.0≦̸X≦̸about 2.5) is satisfied, wherein a content of the SOx occluding agent in the partition walls is expressed by X (mol/L) and a porosity of the at least one honeycomb unit is expressed by Y (%). |
