摘要： An x-ray tube providing excellent assembleability and handleability. An electrically conductive metallized layer 11 is provided on the surface of a stem 3. Therefore, when the x-ray tube 1 is being produced, thermally fusing nature of brazing material A provided between the stem 3 and the lower edge portion 8a of the focussing electrode 8 can be improved by the metallized layer 11. Further, the metallized layer 11 extends from the lower edge portion 8a of the focussing electrode 8 to the low voltage cathode pin 5a. Therefore, electric continuity between the focussing electrode 8 and the low voltage cathode pin 5a is achieved on the surface 3a of the stem 3. There is no need for separate wiring operations after the x-ray tube 1 is assembled. Connection between the focussing electrode 8 and the cathode pin 5a can be completed simultaneously with completion of the brazing connection.
