Vehicle electronic control unit

In a vehicle electronic control unit, a power device (21) and a circuit component (22-25), which structure a circuit in which current flows when the power device (21) is driven, and a printed board (31) are disposed within an aluminum case (30) as a housing. Both the power device (21) and the circuit component (22-25) are disposed within a resin mold unit (40) in a state where both the power device (21) and the circuit component (22-25) are wired so that a loop circuit is structured as a current path. Both the power device (21) and the circuit component (22-25) are mounted on the printed board (31) by using a connection terminal (41) which protrude from the resin mold unit (40). According to the vehicle electronic control unit, noise and efficiency of the circuit can be improved because a loop of large current can be reduced.
