Simplifying a control system by integrating current control for an exciting coil and a main current control for a starter motor is accomplished by a current control unit for a starter motor and is constructed with a control device provided among a battery, a motor contact point and an exciting coil, and a starter ECU for driving the control device. The control device has a device capacity for allowing main current of the starter motor. The starter ECU changes a control specification for the control device before and after closing the motor contact point. That is, control-start timing of a coil current is determined by a battery voltage before closing the motor contact point. Thereafter, the coil current is restricted to a predetermined value to reduce a moving speed of a plunger. After closing the motor contact point, the main current is slowly raised.
