In a starter for starting an internal combustion engine with a first output shaft to which a ring gear is coupled, a motor has a second output shaft to which a movable pinion member is coupled and is operative to, when energized, rotate the second output shaft. A solenoid device includes a solenoid actuator linked to the movable pinion member. The solenoid actuator is configured to, when activated, shift the movable pinion member toward the ring gear to be engaged with the ring gear. The solenoid device includes a solenoid switch configure to, when activated, energize the motor. The solenoid actuator and the solenoid switch are integrated with each other to provide the solenoid device. A controller module is configured to individually control an activation of the solenoid actuator and an activation of the solenoid switch. The controller module is mounted on the solenoid device.
