PURPOSE:To make smooth the surface of a wiring pattern formed by screen print. CONSTITUTION:In a wiring board manufacturing method which prepares a wiring board by forming a wiring pattern 12 on a board 11 by screen print, there is provided a process which allows a wiring board 21B where the wiring pattern 12B is formed on the board 11 by screen print, to pass through rollers 22, and levels the printed wiring pattern 12 by the extrusion force between the rollers 22. This process makes it possible to smooth the surface of the wiring pattern 12 so as to obtain a wiring pattern whose surface is smooth. |
