Honeycomb structure and honeycomb filter

Abstract

A honeycomb structure includes: a pillar shaped honeycomb substrate 10 having porous partition walls 12 that define a plurality of cells 11, each of the cells 11 extending from an inflow end face 14 to an outflow end face 15 of the honeycomb substrate 10 to form a flow path for a fluid; and a porous outer peripheral coating layer 13 disposed on an outer peripheral surface of the honeycomb substrate 10, wherein the honeycomb substrate 10 includes pores having a pore diameter that causes capillary action in the partition walls 12, and wherein, when an average pore diameter of the honeycomb substrate is B [μm], and an average pore diameter of the outer peripheral coating layer is A [μm], a relationship of B<A is satisfied.
