1. An X-ray inspection apparatus comprising:
an X-ray tube configured to irradiate an article with an X-ray;
a transport conveyor configured to transport the article in one direction such that the article passes through an irradiation space of the X-ray emitted from the X-ray tube;
an X-ray sensor configured to detect the X-ray transmitting through the article; and
an X-ray shielding door disposed on one side of a width direction with respect to the transport conveyor to open the irradiation space to an outside in an open state and to prevent the X-ray from leaking from the irradiation space in a closed state, the width direction being orthogonal to both a transport direction of the article and a vertical direction,
wherein at least a part of an inner surface of the X-ray shielding door includes an inclined portion that is inclined downward from the one side toward an other side in the width direction with respect to the transport conveyor when seen in the transport direction in the closed state, and
in the closed state, a lower end portion of the inclined portion in the vertical direction is located closer to the other side of the width direction than a position of an end portion of the transport conveyor on the one side of the width direction.
