Abstract
In an electronic control unit, a drive element liable to generate heat and a control processing element liable to be affected by heat are respectively mounted on a drive circuit board and a control circuit board different from each other, and the two boards are connected to each other by a flexible printed circuit board. The bonding portion of the flexible printed circuit board to the control circuit board is a back side portion of a connector mounted on the control circuit board at the same side as the control processing element. Therefore, heat generated by the drive element is suppressed from being transferred to the control processing element without causing layout hindrances.
