The present invention provides a honeycomb structure formed by combining a plurality of porous honeycomb blocks through a bonding material layer A, wherein the porous honeycomb block is formed by connecting a plurality of porous honeycomb units through a bonding material layer B The porous honeycomb unit is composed of a combination of partition walls defining a plurality of cells forming a flow path of a fluid, and an outer peripheral wall positioned at the outermost periphery. At least a part of the bonding material layer A has higher toughness than the bonding material layer B. |
