<p>A method of manufacturing a honeycomb structural body including at least one honeycomb unit including plural cells extending from a first end face to a second end face in a longitudinal direction, the plural cells being partitioned by cell walls, the at least one honeycomb unit including zeolite particles that have undergone iron ion-exchange, the method including (a) a step of performing a heat treatment on the zeolite particles that have undergone the iron ion-exchange, the heat treatment being performed in a non-oxygenated atmosphere having a temperature within a range of 500°C through 800 °C, to obtain heat-treated zeolite particles; (b) a step of forming at least one honeycomb molded body from a raw material including the heat-treated zeolite particles; and (c) a step of manufacturing the at least one honeycomb unit by firing the at least one honeycomb molded body.
