PURPOSE: To obtain a matrix board in which noise is suppressed as much as possible. CONSTITUTION: In a conductor circuit having a matrix-like plan view, conductor circuits 162 , 1822 in the first and third layers for every other row are divided equally. The conductor circuits in the first and third layers thus divided are interconnected being inverted vertically. Conductor circuits 172 , 192 in the second and fourth layers for every other column are also divided equally and interconnected while being inverted vertically. |
