PROBLEM TO BE SOLVED: To provide a drive control circuit for a vehicular starter motor of a simple structure allowing an operator to easily operate and continuing electric power supply to a starter motor and starting an engine and operation of ECU stops, and stopping drive of the starter motor after the engine start for improving reliability of engine start and merchantability. SOLUTION: An NPN type transistor 34 having a collector terminal connected to an exciting coil 14b of a starter relay 14 and having an emitter terminal grounded, a starter switch 22, a 3V electric power source circuit 32, CPU 26 and a logic circuit 36 connected to a base terminal of the transistor 34 are provided. The logic circuit 36 generates high level output when second predetermined voltage lower than a predetermined voltage is supplied and output indicating turning on operation from the starter switch is supplied.
