A honeycomb structure includes a plurality of honeycomb fired bodies and an adhesive layer. The plurality of honeycomb fired body has a longitudinal direction and a plurality of cell walls extending along the longitudinal direction to define a plurality of cells. The adhesive layer is provided between the plurality of honeycomb fired bodies to connect the honeycomb fired bodies. Pore diameters of pores in the adhesive layer are about 300 mum or less. A ratio of a total area of pores having a pore diameter of at least about 50 mum and at most about 300 mum and an aspect ratio of at least about 1 and at most about 1.5 in a cross-section perpendicular to the longitudinal direction to a total area of pores having a pore diameter of at least about 50 mum and at most about 300 mum is about 90% or more.
