A three-dimensional object is obtained by repeating multiple times forming a ceramic powder layer formed of a ceramic powder and applying to a desired region of the ceramic powder layer a liquid precursor composition at least containing at least any one of a metal alkoxide, a metal chloride, a hydrolysate of the metal alkoxide and a polycondensate of the hydrolysate, and water, thereby obtaining a laminated body; subsequently heating the laminated body at a temperature lower than the sintering temperature of the ceramic powder; and removing the ceramic particle in a region to which the precursor composition has not been applied.

A porosity is freely controlled in preparation of a porous polymer film by a phase separation method. A solvent absorption sheet is used for a solvent in a polymer solution so that the coating film of the polymer solution may be covered with the sheet. After that, the solvent in the film is selectively removed. Then, the resultant is immersed in a poor solvent. Thus, a porous polymer film can be produced.
