Patent attributes
A printed wiring board group includes a plurality of printed wiring boards wherein a difference (ΔΩ−AB) between an average electric resistance (A-ave.) of wires formed in one printed wiring board (A) and an average electric resistance (B-ave.) of wires formed in a printed wiring board (B) adjacent to the printed wiring board (A) is within a range of ±5% of an average electric resistance (AB-ave.) of the wires of the printed wiring boards (A) and (B); and a difference (ΔΩ−ab) between an electric resistance (a-3) of an outermost wire of the printed wiring board (A) and an electric resistance (b-3) of an outermost wire of the printed wiring board (B) is within a range of ±11.05%, preferably within a range of ±6.12%, and is particularly preferably within a range of ±6.00% of the average electric resistance (AB-ave.) of the printed wiring boards (A) and (B).
