Fuel injection device

A current control unit in a fuel injection device controls a magnitude of a current flowing through a coil during single energization. A current Ip1 flows once a signal input to the current control unit is turned ON at time t11. As a result, a movable core and a needle abut against each other with a lift amount increased at time t12, and then the needle is separated from a valve seat and pre-injection is performed. At time t13, which follows the pre-injection, the needle and movable core lift amount becomes a lift amount D1 at a time when the needle and the valve seat abut against each other, and temporary valve closing occurs. At time t14, which follows time t13, currents Ix1 and Im1 larger than the current Ip1 are caused to flow through the coil, and then main injection is performed with the needle and movable core lift amount turned into a lift amount D2 larger than the lift amount D1. Therefore, fuel injection can be performed twice during the single energization.
