Method of producing honeycomb structure and honeycomb structure
A method of producing a honeycomb structure includes a step of forming a ceramic block by bonding a plurality of honeycomb units that have a plurality of cells partitioned by cell walls using a bonding layer, or steps of forming a ceramic block of a single honeycomb unit and providing a coating layer on an outer peripheral portion of the ceramic block. The bonding layer or coating layer is provided as a paste of a bonding material or a coating material including particles of a foaming material having a diameter in a range of approximately 1 μm to approximately 50 μm. The method further includes a step of blowing up the foaming material, and a step of evaporating the foaming material and forming bubble marks having a diameter in a range of approximately 100 μm to approximately 300 μm.
