An electronic control unit includes a circuit board, multiple circuit patterns, multiple semiconductor devices, multiple leads, and at least one thermal-conduction limiting portion. Each of the semiconductor devices is installed to the corresponding circuit pattern formed on the circuit board. Each of the leads electrically and mechanically connects each of the semiconductor devices to the corresponding circuit pattern. The thermal-conduction limiting portion, which can limit conduction of heat generated from the semiconductor devices, is placed between corresponding two of the circuit patterns.
