To provide a honeycomb structure of zeolite having a low pressure drop and excellent capability of removing NOx.
The honeycomb structure 100 of zeolite is configured to include a sintered body made by sintering a molded body of a honeycomb shape produced by extrusion-molding of a raw material composition comprising zeolite particles 32, a catalyst support 34 supporting noble metal, and an inorganic binder 33, which honeycomb includes a partition wall 1 that forms a plurality of cells each extending from one end face to the other end face thereof to serve as fluid flow paths. The mean particle diameter of the catalyst support 34 supporting noble metal is at least 10 times as large as that of the zeolite particles 32. The catalyst support 34 supporting noble metal is contained therein in an amount of 5 to 25 vol.% relative to 100 vol.% of the zeolite particles 32. The noble metal is supported on the catalyst support 34 supporting noble metal, in an amount of 0.2 to 2.0 mass% relative to 100 mass% of the zeolite particles 32.
