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.
