ABSTRACT:
A honeycomb structure includes adhesive layers and plural honeycomb units bonded to each other by interposing the adhesive layers between the plural honeycomb units. Each of the honeycomb units has partition walls extending along a longitudinal direction of the honeycomb units to define plural through holes. The plural honeycomb units include a SOx absorbent, inorganic particles, and an inorganic binder. An expression Y≦−0.3X+1.55 (about 1.0≦X≦about 2.5) is satisfied, in which X represents a content (mol/L) of the SOx absorbent in the partition walls and Y represents a ratio B/A in which A represents a Young's modulus of the honeycomb units and B represents a Young's modulus of the adhesive layers.
