Abstract
A short arc lamp in which cylindrical retaining bodies can be easily and reliably attached in upholding parts of the electrodes on a temporary basis and in which also the disadvantages which are caused by an anomalous discharge immediately after starting of lamp operation can be eliminated are achieved in a short arc lamp in which a cathode and an anode opposite one another in an arc tube having side parts on opposite sides, in which the upholding parts of the cathode and anode electrodes are inserted and held in cylindrical retaining bodies, and in which the cylindrical retaining bodies are supported in the shrunken regions of the side tubes by the upholding parts of the electrodes being wound with coil components which border the faces of the cylindrical retaining bodies that face the electrodes, and by the cylindrical retaining bodies being temporarily attached by these coil components. Furthermore, as the coil components, a coil wound which is formed of a flexible foil lead that has been bent in the middle region of the flexible coil lead and wound so that the two ends of the flexible coil lead are located on the side closest to the electrode.
