<p>An electronic device is provided with a wiring board having a first power supply wiring whereupon a first power supply potential is applied and a second power supply wiring whereupon a second power supply potential lower than the first power supply potential is applied; a microcomputer having first and second power supply terminals, wherein the first power supply terminal is connected to the first power supply wiring and the second power supply terminal is connected to the second power supply wiring; and a connector connected to the first and the second power supply wirings. An inductor element for correcting impedance error of the first and the second wirings is connected to either the first power supply wiring or the second power supply wiring in series. Thus, unnecessary electromagnetic emission due to a common mode current can be suppressed.</p>
