Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce the whole number of electric wires when driving solenoid coils of an actuator for a solenoid valve of an engine. SOLUTION: In this engine module, a bridge circuit PWM-driving the respective solenoid coils 22, 23 of the actuator 20 is formed by bus bars 31a-31d, 36, 39a-39h, 43 or an FPC, is housed in a module body 21a, and is directly connected to the actuator 20 via a connector 41 as a switch unit 21. Thereby, a wire harness 38 between the switch unit 21 and the actuator 20 becomes useless to reduce the whole number of the electric wires.
