An X-ray tube includes a tube body that encloses a tube volume in a gas-tight manner. An emitter electrode, a gate electrode, and an anode are arranged within the tube volume. The emitter electrode is an unheated electrode having emitter needles in an area facing the gate electrode, which are themselves arranged on a substrate. The arrangement of the emitter electrode and the gate electrode are coordinated such that applying an emission voltage between the emitter electrode and the gate electrode causes electrons to be emitted from the multitude of emitter needles due to the resulting electrical field. The gate electrode is connected with thermal conductivity via a connecting element to a heat sink arranged outside the tube volume.
