A bottom face processing method of a pillar-shaped honeycomb structure including steps of:

Bottom face processing method of pillar-shaped honeycomb structure, manufacturing method of fired honeycomb structure, and manufacturing method of joined body

A method for producing a honeycomb structure, the method including: a step of drying a pillar-shaped honeycomb formed body including partition walls that define a plurality of cells each forming a flow path penetrating from a first end face to a second end face; and after the step of drying, a step of cooling the honeycomb formed body by applying a suction force to the first end face of the honeycomb formed body to allow a coolant to flow in the honeycomb formed body from the second end face, pass through the cells, and flow out from the first end face.

Method for producing honeycomb structure

A masking method for honeycomb formed body, including bonding a film on at least one bottom face of a honeycomb formed body in a quadrangular prism shape such that an adhesive surface is in contact with the bottom face. The step of bonding the film includes bonding of the film so as to have a bottom face covering portion that covers a whole surface of the bottom face and a pair of outer edge portions along one pair of opposite sides of a quadrangle defining an outer peripheral shape of the bottom face and a pair of protruding portions protruding from another pair of opposite sides of the quadrangle. At least a part of the adhesive surface of each of the pair of protruding portions is bonded so as to be in contact with a pair of opposing lateral faces of the honeycomb formed body.
