Abstract:
1. A manufacturing method of an electrode for a honeycomb structure forming die which forms a honeycomb structure including a plurality of flow-through cells partitioned by porous partition walls, the method comprising: preparing a thick plate-like electrode base body made of an electricity discharging material and having two surfaces; making a plurality of through holes at positions corresponding to the flow-through cells, in the electrode base body; inserting processing electrodes into the plurality of holes, respectively, and discharging electricity from the insides of the holes toward side surfaces of the holes of the electrode base body to process the side surfaces of the holes of the electrode base body into shapes corresponding to the porous partition walls; whereby obtaining an electrode where a plurality of electrode cells partitioned by electrode partition walls appear on at least one of the surfaces thereof.
