PROBLEM TO BE SOLVED: To provide an injector control device capable of improving a valve opening operation characteristic of injectors by simple processing. SOLUTION: When respective injectors reach valve opening time, a valve opening signal is turned on for a predetermined valve opening timeτ. A control circuit turns on a starting signal for a preset timeτp1 when the valve opening signal is turned on when a starter signal shows a driving state of a starter motor, and turns on the starting signal for a preset timeτp2 shorter than the preset timeτp1 when the valve opening signal is turned on when the starter signal shows a stopping state of the starter motor. Therefore, supply time of a starting current supplied to the injectors becomes long for a prescribed period after starting an engine, and becomes short after a prescribed time passes. The prescribed period after starting the engine may be a period until an engine speed reaches a prescribed engine speed, a period until a water temperature of engine cooling water reaches a prescribed value and a period until battery voltage reaches a prescribed value.
