Abstract
In a fuel injector, a body has formed therein a spray hole and a fuel supply passage. Fuel supplied to the fuel supply passage is delivered to the spray hole. A fuel pressure sensor produces a signal indicative of a pressure of the fuel. First terminals are attached to the fuel pressure sensor, and include a terminal for outputting the signal. The fuel pressure sensor is threadedly installed in the body while the plurality of first terminals are rotated about a preset axis. A connector includes a housing attached to the body, and second terminals supported by the housing for external electric connection of the fuel pressure sensor. Electrodes are each arranged to extend around the preset axis in a circular arc. Each of the electrodes electrically connects a corresponding one of the first terminals to a corresponding one of the second terminals.
