PROBLEM TO BE SOLVED: To provide an electronic controller including a circuit board that can be diverted easily as the circuit board of an electronic controller simply performing the basic function, without changing a bypass capacitor, and performing both the basic function and additional functions.SOLUTION: In a first region 10 of a printed wiring board, basic circuit components performing the basic function are mounted, and in the second region 30, additional circuit components performing additional functions are mounted. The basic circuit components include an operation voltage generation circuit 14 for supplying an operation voltage to at least some of the basic circuit components and additional circuit components, and a bypass capacitor 25 for the additional circuit components. The bypass capacitor 25 is connected with a power supply wiring pattern 12a for supplying operation voltage to the additional circuit components, and arranged at a position closer to the second region 30 than the operation voltage generation circuit 14, in the first region 10. |
