PROBLEM TO BE SOLVED: To provide a print circuit board capable of reducing noise generation by maintaining connection impedance between the print circuit board and a housing low and suppressing generation of a potential difference of a GND level, and enabling an accurate GND connection at the same time.SOLUTION: The print circuit board includes a plurality of through holes 5 for contacting the print circuit board to a housing 3 in a neighborhood of a screw hole of a conductor land 11 that is electrically coupled to a screw hole 8 for screw coupling to mount the print circuit board 2 to the GND-coupled housing 3. |
