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 m/g and less than or equal to approximately 800 m/g. An external surface area of the zeolite is more than or equal to approximately 40 m/g and less than or equal to approximately 80 m/g.

A honeycomb structure includes a honeycomb unit having a plurality of through holes defined by partition walls along a longitudinal direction of the honeycomb unit. 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 obtained by ion-exchange with iron ions and an inorganic binder. A specific surface area of the zeolite is more than or equal to approximately 500 m/g and less than or equal to approximately 800 m/g. An external surface area of the zeolite is more than or equal to approximately 40 m/g and less than or equal to approximately 80 m/g.

A silico-alumino phosphate includes Si, Al, and P. A ratio of an amount of substance of Si to a sum of an amount of substance of Al and an amount of substance of P is approximately 0.22 or more and approximately 0.33 or less. An acid point is approximately 1.2 mmol/g or more. A honeycomb structural body includes a honeycomb unit. The honeycomb unit includes the silico-alumino phosphate and an inorganic binder. The honeycomb unit has a plurality of through-holes divided by a plurality of partition walls and arranged in a longitudinal direction of the honeycomb unit. An exhaust gas conversion apparatus includes the honeycomb structural body, a holding sealing member and a metal pipe. The holding sealing member is provided at an outer peripheral portion of the honeycomb structural body. The honeycomb structural body and the holding sealing member are installed in the metal pipe.
