Abstract
Provided is a box-type vehicle-mounted control device that effectively increases the amount of heat transfer from electronic components and a circuit board to a casing (base and cover) and that accordingly has achieved excellent heat dissipation property. The box-type vehicle-mounted control device includes a circuit board, a base, and a cover. In addition, a first heat radiating coating layeris formed on at least one surface of the circuit board, and a second heat radiating coating layeris formed on an inner surface of one or both of the baseand the coverfacing the first heat radiating coating layer
