Target for x-ray generator, method of manufacturing the same and x-ray generator

A target for an X-ray generator which is placed inside the X-ray generator and is irradiated with accelerated electrons to generate an X-ray, comprising:

• a holder part made of an electrically conductive material and having an opening part;
• a diamond plate air-tightly joined to the holder part so as to close the opening part;
• a thin film target provided on a surface of the diamond plate, with its outer peripheral part extending to the holder part to be electrically connected to the holder part,
• wherein the holder part is configured to be electrically connected to a power supply of the X-ray generator, and
• the diamond plate is incorporated into the X-ray generator with one side disposed in a vacuum atmosphere where the thin film target is formed, and an opposite side thereto disposed at a side where the diamond plate is brought into thermal contact with a refrigerant and cooled.
