A printed circuit board structure for a motor driving device in which the number of kinds of printed circuit boards for constituting inverter devices having different allowable input voltages are reduced. This printed circuit board structure comprises a plurality of conductive patterns (2A, 2B) and a selective connector (5). Each of the conductive patterns includes at least one pair of electrodes (3) arranged in confronting relation to form a capacitor, and terminals (41a, 41b, 42a, 42b) electrically conducted with the electrodes. The selective connector selectively connects the terminals of the conductive patterns so that a capacitor circuit having predetermined capacitance is formed. <IMAGE>
