PROBLEM TO BE SOLVED: To provide an injector control device which can ensure proper injection characteristics even when injection ending is in the vicinity of switching of a fixed current value. SOLUTION: Relating to solenoids 101a, 102a, 103a, 104a for valve opening injectors 101, 102, 103, 104 for a Diesel engine, first the solenoid is fixed current- controlled for a prescribed period by a first prescribed current value, after the prescribed period, fixed current control is performed to the current carrying stop timing in accordance with an injection amount by a second prescribed current value lower than the first prescribed current value. An ECU 200, judging the current carrying stop timing in accordance with the injection amount for whether it is shorter or longer than the prescribed period, advances the current carrying stop timing when it is judged shorter or delays the current carrying stop timing when it is judged longer.
