Abstract:
1. A manufacturing method of a honeycomb structure, comprising: a step of coating a surface of each of a plurality of releasing sheets with a paste for an electrode, to prepare electrode forming sheets in which the surface of each of the releasing sheets is provided with an electrode paste film, wherein a thickness of the releasing sheets is from 38 to 300 μm; a formed honeycomb body with the electrode forming sheets forming step of attaching the electrode forming sheets to a side surface of a tubular formed ceramic honeycomb body which is a curved surface, the formed ceramic honeycomb body having partition walls with which a plurality of cells extending from one end surface to another end surface are formed to become through channels of a fluid, and an outer peripheral wall positioned at the outermost periphery, so that the electrode paste films adhere on the side surface of the formed ceramic honeycomb body, to prepare a formed honeycomb body with the electrode forming sheets which is the formed ceramic honeycomb body having the side surface provided with the electrode forming sheets; and a honeycomb structure forming step of firing the formed honeycomb body with the electrode forming sheets, or removing the releasing sheets from the formed honeycomb body with the electrode forming sheets to form the formed honeycomb body with the pastes for the electrodes, and then firing the formed honeycomb body with the pastes for the electrodes, to obtain a honeycomb structure having the side surface provided with the electrodes of uniform thickness.
