PROBLEM TO BE SOLVED: To provide a power supply device to apply to a focusing electrode of an X-ray tube provided with the focusing electrode, and the power supply for X-ray generation in which an output voltage of the power supply is constituted variable, and in which fluctuation correction of an X-ray focus position, diversification of focus size, quickening of explosive emission and stopping of the X-ray, and positive focus movement and tube current control are possible. SOLUTION: The power supply device comprises a high voltage generating means 10 to apply a direct current high voltage to an X-ray tube 6, and an electron beam deflecting voltage generating means 30 to apply the voltage between the focusing electrodes 62b and 62c to the X-ray high voltage device constituted of a filament heating means 20. A high voltage connector 8 having filament terminals 81, 82 and terminals 83, 84 to which a focusing electrode voltage is applied, and the high voltage connector 9 having output terminals 91, 92 of the filament heating means 20 and the output terminals 93, 94 of the electron beam deflecting voltage generating means are installed, and by connecting these with a high voltage cable 7, the high voltage generating means 10, the filament heating means 20, and the electron beam deflecting voltage generating means are connected to the X-ray tube.
