X-ray generation apparatus and X-ray imaging apparatus

An X-ray generation apparatus comprising:

• an X-ray generation tube including an insulating tube with a first opening end and a second opening end, a cathode arranged to close the first opening end of the insulating tube and including an electron emitting portion, and an anode arranged to close the second opening end and including a target that generates X-rays when electrons from the electron emitting portion collide;
• an electronic component having an electronic terminal electrically connected to the cathode, the electronic component being arranged in proximity to the cathode;
• a driving circuit configured to drive the X-ray generation tube via the electronic component;
• an accommodating container configured to accommodate the X-ray generation tube, the electronic component, and the driving circuit;
• and
• a member arranged to contact an outer surface of the cathode and the electronic component, the member being arranged spaced apart from the accommodating container;
• and
• wherein the accommodating container has a third opening end, and the X-ray generation tube is arranged to close the third opening end,
• the accommodating container is filled with an insulating liquid,
• the accommodating container defines a first space storing at least a part of the driving circuit, and a second space protruding from the first space and storing the X-ray generation tube and the electronic component,
• the accommodating container includes a protrusion portion surrounding the second space, and one end of the second space forms the third opening end.
