PROBLEM TO BE SOLVED: To provide a method for production of a ceramic film complex, capable of forming a favorable ceramic film on the surface of a porous substrate cell.SOLUTION: A ceramic film precursor 25 is formed by applying a precursor sol 21 on the surface of the cell 2 of a porous substrate 10 through the steps of: disposing at one edge 11 of the porous substrate 10, a container 20 for storing the precursor sol which has a liquid discharge port 20a having a larger opening than the region in which the cell 2 is formed in one ridge 11 of the porous substrate 10; and making the precursor sol 21 stored in the container 20 free-fall from the whole area of the liquid discharge port 20a of the container 20 toward one edge 11 of the substrate 10 in such a state that the porous substrate 10, on which the container 20 is disposed, is arranged so that one edge 11 is disposed upward and the direction L to which the cell of the substrate 10 extends becomes vertical. |
