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. 1. A formation process of a pattern characterized in 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.2. The formation process of a pattern according to claim 1 , wherein the blanket is sheet-formed.3. The formation process of a pattern according to claim 1 , wherein the blanket is roll-formed.4. The formation process of a pattern according to claim 1 , wherein an electrode pattern is formed using an electroconductive paste.5. The formation process of a pattern according to claim 4 , wherein the electrode pattern is a wiring electrode to be used in a touch panel claim 4 , a solar cell claim 4 , a laminated ceramic capacitor claim 4 , an antenna claim 4 , and a multilayer printed wiring board.6. The formation process of a pattern according to claim 1 , wherein a first pattern is printed on the blanket by a screen printing process using an electroconductive ...
