    摘要： Conventionally, the magnetic field generator 4 was arranged perpendicularly to the axis O of the electron beam B. The magnetic field generator 4 of this invention is arranged so as to be inclined relative to the axis V perpendicular to the axis O of the electron beam B. Specifically, the magnetic field generator 4 is arranged so as to be inclined relative to the axis V perpendicular to the axis O of the electron beam B within the range in the cathode 2 side from the focused and deflected electron beam B. Inclination up to the anode 5 side opposite to the cathode 2 side will lead to a possibility of increasing the reduced X-ray source diameter. Thus, arranging the magnetic field generator 4 so as to be inclined within the range in the cathode side from the electron beam B may reduce the X-ray source diameter.
