A zeolite structure having excellent exhaust gas purification performance and strength is provided. SOLUTION: A honeycomb-shaped zeolite base material 4 having partition walls 1 for partitioning and forming a plurality of cells 2 extending from one end face 11 to the other end face 12 serving as a fluid flow path is provided, and the partition walls 1 are made of metal ions. It contains ion-exchanged zeolite, and the pore diameter distribution of the partition wall when the horizontal axis is the pore diameter and the vertical axis is the log differential pore volume is the first maximum in the range of the pore diameter of 0.002 to 0.05 μm. The first maximum value which is represented by a curve having a point and a second maximum point in the range of the pore diameter of 0.06 to 10 μm, which is the maximum value at the first maximum point, is represented by the second maximum point. A zeolite structure 100 having a value obtained by dividing the second maximum value, which is a maximum value, by 1.0 to 20. [Selection] Figure 1 |
