Abstract
By providing a manufacturing method of an electrode for a honeycomb structure forming die including: preparing a thick plate-like electrode base body made of an electricity discharging material and having two surfaces; making a plurality of holes in the electrode base body at positions corresponding to flow-through cells; inserting processing electrodes into the holes, 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.
