Abstract
In the present invention, a honeycomb structure includes a joined honeycomb segment body in which a plurality of honeycomb segments are integrally joined by mutual joining surfaces via a joining material layer, and has a configuration in which a plurality of cells to become through channels of a fluid are arranged in parallel with one another along a central axis direction. The joining material layer contains, as aggregates, inorganic particles, and acicular crystal particles having a shot content ratio smaller than 10 mass %, and the acicular crystal particles include 80 mass % or more of acicular crystal particles having an average length of 20 to 500 μm in a long axis direction of the acicular crystal particles. As the inorganic particles, silicon carbide, cordierite, alumina, zirconia, yttria or the like can be used, and as natural acicular minerals, sepiolite, wollastonite, palygorskite or the like can be used.
