ABSTRACT:
An electronic device comprising: a wiring substrate having a first power-supply wiring to which a first power-supply potential is applied and a second power-supply wiring to which a second power-supply potential lower than the first power-supply potential is applied; a microcomputer having first and second power-supply terminals in which 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 second power-supply wirings, wherein an inductor element for correcting an impedance error of the first and second wirings is connected in series to either one of the first and second power-supply wirings. According to such configuration, unnecessary electromagnetic radiation posed by a common current can be suppressed.
