To sufficiently reduce a height of a driving control device in a vertical direction to miniaturize the whole device and improve a degree of freedom of layout.
In a driving control device driving and controlling an electric motor of an electric power steering device, a power electronic circuit supplying a power to the electric motor and a filter electronic circuit removing an electromagnetic noise at energization are formed integrally to a bus bar assembly 13 molded from a resin material, and a control substrate 14 configuring a control circuit controlling to drive the electric motor is polymerized and arranged to the bus bar assembly. Six semiconductor switch elements 21 arranged to a lower surface of the bus bar assembly are held in a holding state between the bus bar assembly and a swollen part 5 of a plate-like housing main body 3 that is a heat radiation member via two heat radiation sheets 9.
