Abstract
A honeycomb structure includes periphery honeycomb fired bodies which include at least a single piece of a periphery small honeycomb fired body having in the cross-section a cross-sectional area which is less than about 60% of a cross-sectional area of a single piece of the center-portion honeycomb fired body. A cross-sectional area of a periphery honeycomb bonded body in the cross-section is about 60% or more of the cross-sectional area of a single piece of the center-portion honeycomb fired body. The second adhesive layer is provided between the periphery small honeycomb fired body and the at least one piece of the honeycomb fired body. The second adhesive layer has thermal conductivity higher than thermal conductivity of a first adhesive layer. The second adhesive layer has Young's modulus higher than Young's modulus of the first adhesive layer. The center-portion honeycomb fired bodies are bonded together with the first adhesive layer.
