To provide a method for manufacturing a honeycomb structure forming die for more easily manufacturing the die for extruding the honeycomb structure with the sizes of cells different between the inflow side and the outflow side of a fluid to be processed.
The method for manufacturing the honeycomb structure forming die includes: an introduction hole forming step for forming, in plate-shaped die substrate having one side end face and the other side end face, a plurality of introduction holes for introducing kneaded clay on the other side end face to function as a kneaded clay introduction face; and a slit forming step for forming slits communicating with the introduction holes in order to form the partition walls of the honeycomb structure by extruding the kneaded clay by performing a comb-like electro-discharge machining by a comb-like electrode 21 where a plurality of plate-shaped protrusion electrodes 23 corresponding with the width of the slits are disposed on the one side end face to function as a kneaded clay formation face of the die substrate.
