Honeycomb structure

摘要

A honeycomb structure (1) includes a honeycomb unit (2) containing zeolite and an inorganic binder and having a shape in which a plurality of cells (3) extending from one end to the another end along the long length direction of the honeycomb unit (2) are separated by cell walls (4). An amount of zeolite contained per apparent unit volume of the honeycomb unit (2) is 230 g/L or more, and mathematical formulae [1] and [2] are satisfied when the thickness of the cell wall (4) is defined as X mm, and the porosity of the cell wall (4) is defined as Y%. 40 �¢ X + 20 ‰¤ Y ‰¤ 40 �¢ X + 30 0.15 ‰¤ X ‰¤ 0.35
