摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device and its manufacturing method for restraining cost. SOLUTION: This fuel injection device is composed of a hollow body for storing a throttle valve for injection, and the valve has a calibration pipe for discharging fuel from a control chamber. The calibration pipe is normally closed and held by a shutter controlled by an electromagnet composed of a magnetic core and an electric coil stored in an annular slot of the core. The coil has a cylindrical outside surface, and the outside surface forms a clearance surrounded by the fuel sent out of the calibration pipe together with the annular slot. The coil is particularly composed of a bobbin having a pair of branch parts for supporting a pair of plugs for supplying electricity of the coil. The plugs are included in a block of at least a partially nonmagnetic material. The bobbin has a substantially cylindrical rib and flanges parallel in two planes. One of the flanges is adjacent to an end part of the plugs, and the other has a small diameter for forming a flow passage for the fuel between the calibration pipe and the clearance.
