摘要： This X-ray tube device (100) includes an anode (2) and a cathode (1) including an emitter (10) emitting an electron to the anode. The emitter includes an electron emission portion (11) in a flat plate shape, a pair of terminal portions (12) extending from the electron emission portion, connected to an electrode (1a), and a supporting portion (13) provided separately from the terminal portions, insulated from the electrode, supporting the electron emission portion.

摘要： The X-ray tube device (100) comprises an anode (2) and a cathode (1) that emits an electron to the anode. The cathode comprises an electron emission element (11) having an electric pathway (111) formed as a flat-plate; one pair of terminals connected to the electrode, and support members (13a, 13b) that support an electron emission element, which is independently installed from the terminal and insulated against the electrodes. And, the terminals include an enlargement member (121, 122) having a cross-section area, in which the cross-section area in the orthogonal direction to the extending direction of the terminals, is larger than the cross-section area of the electric current pathway in the orthogonal direction to the extending direction of the electric current pathway.
