Abstract
A honeycomb structure includes: a honeycomb structure portion including: an outer peripheral wall; a partition wall disposed on an inner side of the outer peripheral wall, the partition wall defining a plurality of cells, each of the cells extending from one end face to other end face to form a flow path, wherein the outer peripheral wall and/or the cells include at least one slit containing a filling material layer made of a filling material, wherein the filling material layer has pores, and wherein the pores having a pore diameter of 90 μm or more account for 30% by volume or more of all the pores contained in the filling material layer.
