There is disclosed a method of controlling pore characteristics (porosity, average pore diameter, and total pore volume) of a porous structure, capable of manufacturing a porous structure having stable pore characteristics, even when fluctuation of a pore forming ratio of an materials to be used for extrusion differs with each lot. In the method of controlling the pore characteristics of the porous structure, a part of an materials to be used for extrusion of the porous structure is sampled and extruded, the pore characteristics of an obtained formed article or a characteristic of the materials to be used for extrusion are grasped beforehand, and the pore characteristics of the extruded/formed article and the fired article are controlled.
