Abstract:
1. 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; a connector connected to the first and second power-supply wirings; and a bypass capacitor connected in parallel to the first and second power-supply wirings, wherein, in between the power-supply terminal of the microcomputer and the bypass capacitor, 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.
