An ECU (30) as a fuel injection control device comprises: an injector control unit (31) that drives and opens a fuel injection valve (21) by passing a current through a magnetic circuit (56) of the fuel injection valve (21) with a predetermined injection pulse (P1), and that passes a current through the magnetic circuit (56) with a predetermined current-passage pulse (P2) within a range in which a needle valve (53) of the fuel injection valve (21) is not driven; and a storage unit (33) that stores information on the behavior of a drive voltage (minus terminal voltage Vm) of the fuel injection valve (21) when a current is passed through the magnetic circuit (56) by the injector control unit (31) with said current-passage pulse (P2). |
