Furthermore, the following embodiments do not limit the invention covered by the claims. Although multiple features are described in the embodiments, not all of these multiple features are essential to the invention, and multiple features may be combined at will. Additionally, in the attached drawings, the same reference numerals are assigned to identical or similar components, and redundant descriptions are omitted. In the following description, directions are explained according to the XYZ coordinate system. FIG. 1 illustrates a schematic cross-sectional view of the configuration of an X-ray generating device (100) of one embodiment. The X-ray generating device (100) may comprise an X-ray generating unit (12), a driving circuit (14) for driving the X-ray generating unit (12), a receiving container (20) for housing the X-ray generating unit (12) and the driving circuit (14), and an insulating component (50) disposed within the receiving container (20). The X-ray generating unit (12) may have a first bottom surface (126) including a radiating unit (122) for emitting X-rays, a second bottom surface (127) opposite to the first bottom surface (126), and a side surface (128) with respect to geometric shape. The X-ray generating unit (12) may have a cylindrical shape, for example. The X-ray generating unit (12) may include an insulating tube (124), an anode (123) including a radiating unit (122), and a cathode (125) including an electron emitting unit (121) that emits electrons. The anode (123) may be positioned at one end of the insulating tube (124) to form a first bottom surface (126), and the cathode (125) may be positioned at the other end of the insulating tube (124) to form a second bottom surface (127). The radiating unit (122) may include a target that generates X-rays by receiving electrons emitted in the forward direction of the Z-axis from the electron emitting unit (121), and a target holding support that holds and supports the target. The driving circuit (14) receives a voltage supplied from the outside and can generate one or more negative driving potentials to drive the X-ray generator (12). The X-ray generator (12) is configured, for example, as an X-ray generator with an anode grounding method, and the anode (123) of the X-ray generator (12) can be electrically connected to a receiving container (20). The negative potential generated by the driving circuit (14) can be supplied to the cathode (125) of the X-ray generator (12) through a cable (16). The driving circuit (14) can generate a potential difference of, for example, 100 kV (e.g., -100 kV). The cable (16) may include a conductive member and an insulating material covering the conductive member, but it is not required to have said insulating material. The X-ray generator (12) and the driving circuit (14) are heat sources. Insulating liquid (e.g., insulating oil) may be filled in the space between the receiving container (20) and the insulating component (50), and in the internal space of the insulating component (50). The cathode (125) of the X-ray generator (12) and the receiving container (20) are electrically insulated. The receiving container (20) may have a shape in which the portion where the X-ray generator (12) is placed protrudes more than the periphery of said portion. In another aspect, the receiving container (20) may have a shape in which the central portion containing the portion where the X-ray generator (12) is placed protrudes mo
