Provided is an air-permeable sheet () to be used in a state of being interposed between a suction stage () and an air-impermeable substrate () when printing is performed by a sheet-fed method on the surface of the substrate () fixed by suction to the suction stage (), the air-permeable sheet capable of printing a desired printing pattern on the surface of the substrate with high accuracy. The air-permeable sheet () includes a non-woven fabric layer () and a support layer () constituted by a woven fabric or knitted fabric.

Air-permeable sheet

The invention provides a process and an apparatus for producing a high quality electronic component by reducing sagging at pattern side walls, which may occur when patterns of a wiring, an electrode, etc. are printed by a screen printing process using an electroconductive paste, an insulation paste, or a semiconductor paste, and reducing a mesh mark on the patterns of a wiring, an electrode, etc., or a full solid surface film, as well as a pattern formation process, by which screen printing can be applied and double face printing can be conducted with the number of process steps less than a conventional process. A pattern is formed by that a pattern is printed on a blanket having a surface comprising polydimethylsiloxane using an electroconductive paste, an insulation paste, or a semiconductor paste by a screen printing process, and the pattern is transferred from the blanket to a printing object.
