Abstract
An emitter that can be lighted even if a line of any part thereof is broken by ensuring an electric pathway. The X-ray tube device includes an electron emission surface P having an electric pathway; electric heating elementsthat are connected electrically to both ends of said electron emission surface; and two branched terminals that are branched in the middle of the electric pathway of the electron emission surface P between electric heating elementsand; second electric heating element, in order from the electric heating elementas the supporting elementand the supporting element; and further comprises: a relayA that switches the electric heating elementand the supporting elementto be in a short-circuit/open condition and a relayB switches the electric heating elementand the supporting elementto be in a short-circuit/open condition. A bypass electric pathway may be formed where the short-circuit condition is switched on and such bypass electric pathway can exist at all locations relative to the electric pathway between the electric heating elementsand
