PROBLEM TO BE SOLVED: To prevent noise from entering a wiring pattern through which a small current flows, while suppressing an increase in the number of components in an electronic control device.SOLUTION: When viewed from the thickness direction of a printed wiring board, a large-current region R1 in which an inner layer pattern for large current is formed and a small-current region R2 in which an inner layer pattern for current is formed are arranged so as not to overlap each other. |
