PROBLEM TO BE SOLVED: To provide an electronic control device that allows efficiently and surely radiating heat occurring in a plurality of switching elements of a drive circuit.SOLUTION: A first wiring pattern 111 in which electrical wiring lines 111a, 111b, and 111c of upstream-side switching element groups 101, 103, and 105 are commonalized, and a second wiring pattern 112 in which electrical wiring lines 112a, 112b, and 112c of downstream-side switching element groups 102, 104, and 106 are commonalized are formed on a substrate 30. At least one of the first wiring pattern 111 and the second wiring pattern 112 is a solid pattern. |
