Abstract
An electronic control device for executing fundamental and additional functions includes: a fundamental circuit element that executes the fundamental function; an additional circuit element that executes the additional function; and a printed wiring board having a rectangular shape divided into first and second regions. The fundamental circuit element is mounted in the first region, and the additional circuit element is mounted in the second region. The fundamental circuit element includes an operation voltage generating circuit for supplying an operation voltage to at least a part of the fundamental and additional circuit elements and a bypass capacitor for functioning for the additional circuit element. The bypass capacitor is connected to a power source wiring pattern for supplying the operation voltage to the additional circuit element. The bypass capacitor is arranged in the first region at a position nearer the second region than the operation voltage generating circuit.
