<p>A honeycomb structure is disclosed that includes a honeycomb unit including zeolite and inorganic binder and having a shape in which a plurality of through holes extends in a longitudinal direction of the honeycomb unit, the through holes being separated from each other by interposing partition walls, in which an aperture ratio of a cross section perpendicular to the longitudinal direction is equal to or more than 50% and equal to or less than 65%, and when the cross section perpendicular to the longitudinal direction is divided into two areas, a center area and an outer peripheral area with a boundary line dividing the two areas, each point of the boundary line being equidistant from both a center and an outer peripheral of the cross section, the aperture ratio of the outer peripheral area is greater than the aperture ratio of the center area.</p> |
