  "textContent": "Provided is a control device of a fuel injection device which can stabilize a behavior of a valve even when a voltage of a voltage source varies, and can reduce a deviation of an injection amount. A control device of a fuel injection device includes a valve a coil which generates a magnetic attraction force to attract a movable member which drives the valve and a voltage source. The fuel injection device applies a voltage to the coil on the basis of an injection pulse, causes a drive current to flow to the coil until the current becomes a maximum current to attract the movable member and drives the valve to inject fuel. The drive current flowing to the coil or a voltage of the voltage source is detected before the injection pulse is stopped. In a case where the detected drive current or the voltage is equal to or less than a setting, a width of the injection pulse or an injection pulse different from the injection pulse is corrected to be long.",
