Therefore, the fuel injection control device is configured to measure, as a valve closing time, a time from when energization of the solenoid is finished to when the valve body moves to the valve closing position for each of the plurality of fuel injection valves ; divide an energization time of the solenoid into a plurality of sections to ; calculate, as an average valve closing time, an average value of the valve closing times measured a plurality of times, in each of the plurality of sections to ; calculate a specific valve closing time based on the average valve closing time of at least one section among the plurality of sections to ; and correct the energization time according to the specific valve closing time of each of the plurality of fuel injection valves",
