Abstract
A honeycomb structure includes at least one honeycomb unit. The at least one honeycomb unit has a plurality of through holes defined by partition walls along a longitudinal direction of the honeycomb unit. The honeycomb unit includes zeolite, an inorganic binder, and a noble metal catalyst. The noble metal catalyst is supported in a region of the honeycomb unit. The region extends from one end portion of the honeycomb unit in the longitudinal direction over approximately 1.5% or more to approximately 20% or less of an overall length of the honeycomb unit in the longitudinal direction.
