Abstract
A honeycomb structure includes a honeycomb unit which has zeolite, inorganic binder, and cell walls extending from one end to another end along a longitudinal direction of the honeycomb unit to define cells. An amount of zeolite contained per apparent unit volume of the honeycomb unit is approximately 230 g/L or more. Mathematical formulae [1] and [2] are satisfied when a thickness of the cell walls is defined as X mm and an average pore diameter of a surface of the cell walls observed by a microscope is defined as Y μm:+0.07≦+0.27   [1]approximately 0.15≦≦approximately 0.35   [2].
