Abstract:
There is provided a honeycomb structure including a honeycomb base material including a porous partition wall parent material; plugged portions; and a porous collecting layer disposed on the surface of the partition wall parent material in the remaining cells. A melting point of a material constituting the collecting layer is higher than that of a material constituting the partition wall parent material, a pore surface area per unit volume of the collecting layer is 2.0 times or more a pore surface area per unit volume of the partition wall parent material, and a thickness of a portion of the collecting layer which penetrates into pores of the partition wall parent material is 6% or smaller of that of each of partition walls including the partition wall parent material and the collecting layer.
