Abstract
A honeycomb structure includes a ceramic block including a plurality of honeycomb fired bodies, a first adhesive layer, and a second adhesive layer. The plurality of honeycomb fired bodies includes center-portion honeycomb fired bodies located at a center portion in a cross-section perpendicular to the longitudinal direction and peripheral honeycomb fired bodies surrounding the center-portion honeycomb fired bodies. The first adhesive layer is interposed between the center-portion honeycomb fired bodies to connect the center-portion honeycomb fired bodies. The second adhesive layer is interposed between each of the center-portion honeycomb fired bodies and each of the peripheral honeycomb fired bodies and between the peripheral honeycomb fired bodies. An adhesive strength α between the center-portion honeycomb fired bodies bonded via the first adhesive layer is higher than an adhesive strength β between honeycomb fired bodies bonded via the second adhesive layer.
