PROBLEM TO BE SOLVED: To provide an inexpensive fuel injection control device capable of highly accurately detecting a rotation angle of a crankshaft, a fuel injection control device stably operable by reducing a voltage variation, and a fuel injection control device without requiring a battery. SOLUTION: This fuel injection control device has a generator 2 composed of a rotor 21 rotating with the crankshaft of an internal combustion engine and having a magnet and a stator 23 having a coil (a charging coil 25), a mechanical detection means (a crank angle sensor 3) for mechanically detecting a rotation angle of the rotor 21, an electric detection means (a control circuit 4) for electrically detecting the rotation angle of the rotor 21 by shaping an output voltage waveform of the coil 25, and a control part (a control part 4) for controlling a fuel injection part 83 based on information on the rotation angle of the rotor 21 detected by the mechanical detection means 3 and the electric detection means 4.
