摘要： A high-intensity discharge lamp including an arc tube provided with a heat-resistant translucent discharge vessel forming a discharge space, an electrode structure, a discharge medium charged in the discharge vessel, the discharge medium being composed of a light-emitting metal including mercury and a starting gas, a support member electrically connected with the electrode structure of the arc tube and holding the arc tube and an outer bulb having the arc tube disposed therein along a tube axis and sealed with a support member at an end portion thereof. The electrode structure has an electrode shaft hermetically sealed at each of opposed end portions of the discharge vessel and having a tip portion disposed in the discharge vessel, a coiled electrode wound around the tip portion of the electrode shaft disposed in the discharge vessel, and a recessed portion or a protruding portion formed on the electrode shaft spaced from the coiled electrode. A lighting device with the high-intensity discharge lamp is also described.
