1. An electronic control device applied to a drive control of an electric motor having a dual coil, the electronic control device having drive circuits for two systems corresponding to the dual coil, the electronic control device comprising:
a multilayer wiring board having a plurality of wiring layers and insulating layers that insulate the wiring layers, and wherein
a detecting element configured to detect an operating state of the electric motor is mounted on the multilayer wiring board, and control systems for two systems corresponding to the dual coil are formed by electronic components mounted on the multilayer wiring board,
each of the control systems includes at least a CPU, a pre-driver circuit configured to convert a command signal of the CPU into a control signal of the drive circuit, a capacitor unit and a filter unit,
when projecting the multilayer wiring board onto a plane, the control systems for two systems are arranged parallel to each other with the capacitor unit and the filter unit being arranged along arrangement of the CPU and the pre-driver circuit, and
when projecting the multilayer wiring board onto a plane, the detecting element is positioned so as to be arranged between the two control systems.
