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 12, a base 13, and a cover 14. In addition, a first heat radiating coating layer 31 is formed on at least one surface of the circuit board 12, and a second heat radiating coating layer 32 is formed on an inner surface of one or both of the base 13 and the cover 14 facing the first heat radiating coating layer 31. |
