Abstract

[Problems] To provide means for obtaining, in a short time, an electrode which can manufacture a die including narrow slits to obtain a honeycomb structure including thin partition walls and which does not break or is not deformed during electric discharge machining for obtaining the die including the narrow slits. [Solution] By providing a manufacturing method of an electrode for a honeycomb structure forming die including: arranging a plurality of processing electrodes 161 having a shape which is complementary to that of the flow-through cells, at positions corresponding to the plurality of flow-through cells in the one surface 107B of the electrode base body 102B; discharging electricity from the plurality of processing electrodes 161 toward the one surface 107B of the electrode base body 102B to carve the electrode base body 102B, so that a plurality of electrode cells having a shape which is analogous to that of the flow-through cells are formed in the electrode base body 102B; whereby obtaining a honeycomb electrode where a plurality of electrode cells partitioned by electrode partition walls appear on the one surface.
