Method for manufacturing honeycomb structure

A method for manufacturing a honeycomb structure comprising an outer peripheral side wall and partition walls disposed on an inner peripheral side of the outer peripheral side wall, the partition walls partitioning a plurality of cells forming flow paths from a first end surface to a second end surface, the method comprising:

• preparing a honeycomb formed body by extruding a green body comprising a ceramic raw material, a pore-forming material, a binder, and a dispersion medium through a die that defines opening shapes of the plurality of cells;
• drying the honeycomb formed body to obtain a honeycomb dried body;
• and
• firing the honeycomb dried body to obtain a honeycomb fired body in which a thickness of the partition walls is 50 μm or more and 210 μm or less, and a porosity of the partition walls is 45% to 60%;
• wherein the pore-forming material in the green body comprises a crosslinked starch and an acrylic polymer, and
• the green body comprises 1.0 parts by mass or more of the crosslinked starch with the proviso that a P content in the green body is less than 0.2 parts by mass, with respect to 100 parts by mass of the ceramic raw material.
