Zusammenfassung:	There is disclosed a honeycomb structure which is a catalyst support of a catalyst body in which a time until a catalyst becomes active is short and a purification efficiency is enhanced. A honeycomb structure 100 includes a honeycomb structure part 4 having porous partition walls 1 which form a plurality of cells 2 having a hexagonal cross-sectional shape and extending through the honeycomb structure part from an inflow end surface 11 to an outflow end surface 12 to become through channels of a fluid, and having an outer peripheral wall 5 which is positioned at an outermost periphery. A porosity of the partition walls 1 is from 35 to 60%, an average pore diameter of the partition walls 1 is from 1 to 5 µm, and among the cells 2, incomplete cells 21 which are the cells 2 formed by the partition walls 1 and the outer peripheral wall 5 are plugged from the inflow end surface 11 to the outflow end surface 12.
