Abstract

PURPOSE: To obtain a wiring board wherein adverse effects among wiring lines are decreased by changing the aligning orders of the wiring lines from the main surface of the wiring board to the other main surface of the board by way of through holes, and connecting the lines.
CONSTITUTION: The aligning orders of wiring lines 2 between an input terminal 20 and an output terminal 31 on an insulated layer of a printed wiring board are changed from the main surface of the wiring board to the other main surface by way of through hole groups 21-30 of the wiring board, and the lines are connected. The intervals between the wirings wherein fluctuating signals flow and the wirings which receive electromagnetic effects become long, and mutual induction is decreased. The electrostatic capacitance effect between the neighboring wirings are also decreased. Thus the printed wiring board wherein the adverse effects among the wiring lines are decreased is obtained.
