Abstract
A honeycomb structure includes a honeycomb unit. The honeycomb unit has a plurality of through holes defined by partition walls along a longitudinal direction of the honeycomb unit. The partition walls have a thickness of approximately 0.1 mm to approximately 0.4 mm. The honeycomb unit is manufactured by molding raw material paste by extrusion molding and thereafter by firing the molded raw material paste. The raw material paste contains zeolite and an inorganic binder. A specific surface area of the zeolite is more than or equal to approximately 500 m2/g and less than or equal to approximately 800 m2/g. An external surface area of the zeolite is more than or equal to approximately 40 m2/g and less than or equal to approximately 80 m2/g.
