する導電体を、前記弁本体に対し電気的絶縁を保
たせて当該弁本体の外部へ配設したことを特徴と
する燃料噴射弁。 A nozzle body provided with a guide hole and a needle valve that slides within the guide hole are formed of a conductive material, an insulating layer is provided between the guide hole and the needle valve, and the needle valve is attached to the valve seat of the nozzle body. In a fuel injection valve with a switch function, an electrical connection is made when the needle valve is seated on the valve seat, and an electrical connection is released when the needle valve is lifted from the valve seat by compressing the nozzle spring by the fuel pressure. A sliding body made of a conductive member is provided in a valve body composed of a holder, an intermediate plate, and a nozzle body while maintaining electrical insulation from the valve body, and the sliding body is movable by being pressed by an elastic material. A fuel injection valve characterized in that a conductor that is in sliding contact with the valve body and electrically conductive with the sliding body is disposed outside the valve body while maintaining electrical insulation from the valve body.
