PURPOSE:To provide the manufacturing method, of a printed-wiring board, wherein it can form a continuity hole in the board wish good accuracy and its productivity is high. CONSTITUTION:Parts in which a continuity hole is to be formed in metal thin- film layers 4, 5 formed on both faces of a board 1 formed in such a way that a glass cloth 2 has been impregnated with a resin 3 and hardened are removed. Then, the resin 3 on the board is removed by an atmospheric-pressure glow plasma etching operation 6, a hole is worked, a plating operation 7 is executed to the formed hole, and the continuity hole 8 is formed. |
