Abstract

There is provided a manufacturing method of a honeycomb structure which is capable of efficiently forming electrodes each having a uniform thickness on a side surface of the columnar honeycomb structure, the side surface being a curved surface. The manufacturing method of the honeycomb structure includes a forming step of a honeycomb formed body with non-fired electrodes where there is performed twice a non-fired electrode forming operation in which an electrode paste 31 is attached to a plate 32 including a printing screen 33, a side surface 5 of a formed columnar ceramic honeycomb body 100, the side surface 5 being a curved side surface, is brought into a pressed state by a squeegee 34 via the printing screen 33 of the plate 32, in the state, the ceramic honeycomb formed body 100 is rotated and the plate 32 is linearly moved along the side surface 5 of the ceramic honeycomb formed body 100, and the squeegee 34 allows the electrode paste 31 to permeate the printing screen 33 and coat the side surface 5 of the ceramic honeycomb formed body 100; and a forming step of the honeycomb structure where the honeycomb formed body with the non-fired electrodes is fired to obtain the honeycomb structure.
