Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board operable on a first and a second prescribed voltages. SOLUTION: A printed circuit board 100 includes metallic layers, one of which is split into two parts 104 and 106 which are electrically insulated from each other and substantially flush with each other, and the one part 106 is related to a first prescribed voltage. The other part 104 is related to a second prescribed voltage, and furthermore the board 100 contains first signal pins 105 connected to the electrically insulated part 106 and at least a capacitor 108, connected to the other part 106 insulated electrically from a grounding and the signal pins 105 is given an alternating current path.
