Abstract: A honeycomb structure including a plurality of porous honeycomb block bodies bound via joining material layers A. Each of the porous honeycomb block bodies includes a plurality of porous honeycomb segments bound via joining material layers B, each of the porous honeycomb segment includes: partition walls that defines a plurality of cells to form flow paths for a fluid, each of cells extending from an inflow end face that is an end face on a fluid inflow side to an outflow end face that is an end face on a fluid outflow side; and an outer peripheral wall located at the outermost periphery. At least a part of the joining material layers A has higher toughness than that of the joining material layers B.

Abstract: A method for producing a honeycomb structure for fine particle collection filters. The honeycomb structure includes a plurality of porous honeycomb segments joined together via joining material layers. The method includes the steps of: forming the outer peripheral wall of each of the porous honeycomb segments so as to have a thickness thicker by a grinding margin; drying the porous honeycomb segments each formed by grinding the outer peripheral wall so as to have the thickness thicker by the grinding margin; firing the dried porous honeycomb segments; grinding and removing the grinding margin of the outer peripheral wall of each of the fired porous honeycomb segments; and applying a joining material to each of the porous honeycomb segments with the grinding margin ground and removed, between joining surfaces of each of the porous honeycomb segments, to join the porous honeycomb segments via the joining material layers.

Abstract: An outer periphery coating method of honeycomb structure has coating steps where the honeycomb structure including a ring-like bulge portion is rotated; a coating member is brought into contact with a side surface of the honeycomb structure by pressing a side edge portion of a spatula via a rubber sheet, the coating member including the plate-like spatula in which a specific cut portion is formed in the one side edge portion and the side edge portion provided with the cut portion is an inclined surface inclined on a coating surface side, and the rubber sheet in which a cut is formed so that an end surface of the end portion is parallel to a back surface of the spatula when the end portion is bent along the side edge portion of the spatula; and a slurry coating material is supplied to the side surface of the honeycomb structure.
