Abstract
A fuel injection device includes a fuel injector and a control portion. The fuel injector is inserted into an attachment hole which is placed at a predetermined position of a cylinder head. The fuel injector has a housing in which a coil is provided. At least a part of the housing which accumulates the coil is surrounded over the whole circumference by an inner circumference surface of the attachment hole. The control portion has an increasing control portion and a holding control portion. The increasing control portion increases a current flowing through the coil to a first target value. The holding control portion holds the current to the first target value.
