         6 . The stencil printing plate of  claim 1  wherein the coating layer comprises:
 a first layer formed on the thin primer film and composed mainly of a coupling agent capable of forming, with the thin primer film, a hydrogen bonding and/or an —O-M bonding (M is any one element selected from a group consisting of Si, Ti, Al, and Zr) by condensation reaction; and 
 a second layer formed on the first layer and composed mainly of a water repellent material or a water and oil repellent material. 
 
     
     
         7 . The stencil printing plate of  claim 6  wherein the coupling agent is a coupling agent selected from a group consisting of silane coupling agent, titanate-based coupling agent, aluminate-based coupling agent, and zirconate-based coupling agent. 
     
     
         8 . The stencil printing plate of  claim 1  wherein an amorphous carbon film substantially comprising carbon only or an amorphous carbon film substantially comprising carbon and hydrogen only is formed on an area of the surface of the substrate where the thin primer film is not formed. 
     
     
         9 . A method of producing a stencil printing plate, the method comprising:
 preparing a substrate having formed therein openings corresponding to a printing pattern;   forming a thin primer film directly or indirectly on the substrate by a dry process, the thin primer film containing at least one substance selected from the group consisting of silicon, titanium, aluminum, aluminum oxide, and zirconium; and   forming on the thin primer film a coating layer having water repellence and/or water and oil repellence.   
     
     
         10 . The method of producing a stencil printing plate of  claim 9 , further comprising the step of subjecting the thin film to a plasma process with any one of nitrogen, oxygen, and a mixture gas of nitrogen and oxygen. 
     
     
         11 . A stencil printing plate comprising:
 a printing mesh body;   a thin primer film formed directly or indirectly on the printing mesh body by a dry process and containing at least one substance selected from the group consisting of silicon, titanium, aluminum, aluminum oxide, and zirconium; and   a coating layer formed on the thin primer film and having water repellence and/or water and oil repellence.   
     
     
         12 . The stencil printing plate of  claim 11  wherein the thin primer film further contains oxygen or nitrogen. 
     
     
         13 . The stencil printing plate of  claim 11  wherein the thin primer film contains an Si oxide, a Ti oxide, or a Zr oxide. 
     
     
         14 . The stencil printing plate of  claim 11  wherein the coating layer comprises a fluorine-containing coupling agent. 
     
     
         15 . The stencil printing plate of  claim 11  wherein the coating layer comprises a fluorine-containing silane coupling agent. 
     
     
         16 . The stencil printing plate of  claim 11  wherein the coating layer comprises:
 a first layer formed on the thin primer film and composed mainly of a coupling agent capable of forming, with the thin primer film, a hydrogen bonding and/or an —O-M bonding (M is any one element selected from a group consisting of Si, Ti, Al, and Zr) by condensation reaction; and 
 a second layer formed on the first layer and composed mainly of a water repellent material or a water and oil repellent material. 
 
     
     
         17 . The stencil printing plate of  claim 16  wherein the coupling agent is a coupling agent selected from a group consisting of silane coupling agent, titanate-based coupling agent, aluminate-based coupling agent, and zirconate-based coupling agent.
