Abstract
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.
