燃料噴射弁。 A valve seat formed within a valve body made of a conductive material, a valve member made of a conductive material that is electrically connected to the valve body to form a switch when seated on the valve seat, and an upper end of the valve member. A movable spring seat made of a conductive material attached to the valve body, an external connection terminal provided electrically insulated on the valve body, and an electrical connection between the external connection terminal and the movable spring seat. In the fuel injection valve, the movable spring seat, the external connection terminal, and the set spring are electrically insulated, and the set spring swings. By doing so, a conductive member is provided via an electrically insulating member at a predetermined location of the set spring that does not contact the valve body, and the movable spring seat and the external connection terminal are electrically connected by the conductive member. Characteristic fuel injection valve.
