Abstract
An injector has a body that defines a high-pressure passage for passing high-pressure fuel to an injection hole inside, a needle that is accommodated in the body and that opens and closes the injection hole, an electric actuator that causes the needle to perform the opening and closing action, a lead wire that is arranged in a lead wire insertion hole formed in the body and that supplies an electric power to the electric actuator, and a fuel pressure sensor that is fixed to the body and that senses pressure of the high-pressure fuel. An outlet hole, via which the lead wire extends from the lead wire insertion hole to an outside of the body, is located at a position closer to the injection hole than the fuel pressure sensor is.
