Summary:PROBLEM TO BE SOLVED: To provide a production method of an open pore type porous body by which the formation of a fine pore layer is uniform and stable on an inclined open pore type porous laminated body, and the arrangement of the particle, etc., optimized. SOLUTION: The open pore type porous body having a fine pore film on the surface of the open pore type porous laminated body inclined such that fine pore diameters become successively small toward the surface or a fine pore layer across a slight depth from the surface is produced with this production method, and the thin film or the surface layer is formed at least with either one method among a vapor chemical reaction method, a vacuum deposition method, an ion plating method or a sputtering method on the surface of the open pore type porous laminated body.
