PROBLEM TO BE SOLVED: To highly-accurately control an injection amount by eliminating an anxiety for reversely correcting an increase and decrease of the injection amount.SOLUTION: A fuel injection control device comprises: electricity-carrying time calculation means which calculates an electricity-carrying time to a coil according to a target injection amount; and rise control means which applies a boost voltage to the coil accompanied by a start of the electricity-carrying, and raises a current flowing in the coil up to a prescribed threshold. Then, in the case that a range in which a time at which the current is raised up to the prescribed threshold and reaches a peak value appears according to a use temperature range of the coil is called as a peak appearance range W1, the target injection amount is set so that a finish time of the electricity-carrying tine Ti becomes a time which is displaced from the peak appearance range W1. |
