A honeycomb structure (1) is disclosed that includes a honeycomb unit (2) having a shape in which plural cells (3) extend along the longitudinal direction from one end face of the honeycomb unit (2) to the another end face, the cells (3) being separated from each other by cell walls (4). The honeycomb unit (2) includes zeolite; inorganic particles; and inorganic binder. The honeycomb unit (2) is characterized in that a hydroxyl group content in the inorganic particles is greater than a hydroxyl group content in the zeolite. |
