A honeycomb structure includes at least one honeycomb unit having a longitudinal direction. The honeycomb unit includes SOx storage agent, inorganic particles, inorganic binder, and a partition wall extending along the longitudinal direction to define plural through holes. An expression Y>=-26X+40000 (0<X<=approximately 500) is satisfied, wherein "X" represents an amount [g] of SOx stored in the honeycomb structure, and "Y" represents a specific surface area [m2/L] of the honeycomb structure when "X" [g] of SOx is stored in the honeycomb structure.
