X-ray generator and X-ray inspection apparatus including the same

An X-ray generator comprising:

• an X-ray tube that generates X-rays;
• a high-voltage circuit substrate that applies a high voltage to the X-ray tube;
• and
• a housing which is filled with an insulating oil and in which the X-ray tube and the high-voltage circuit substrate are accommodated,
• wherein a shielding cover made of a shielding material which shields the X-rays is provided in the housing,
• wherein the X-ray tube is disposed in the shielding cover,
• wherein the high-voltage circuit substrate is attached to an outside of the shielding cover,
• wherein the housing has one side surface which is open, and has a lid body which closes an opening of the one side surface,
• wherein the lid body is formed with an X-ray window portion through which the X-rays generated by the X-ray tube pass, and
• wherein the shielding cover and the X-ray tube are attached to the lid body.
