Abstract

Provides is an X-ray generation device, an X-ray fluoroscopic image photographing device and a CT image photographing device; the X-ray generation device is capable of facilitating the electrical connection of terminals of an X-ray tube to terminals of a high voltage generation part, capable of preventing wiring bodies which connect these terminals from contacting with each other, and capable of preventing the wiring bodies from separating from the terminals of the X-ray tube or the terminals of the high voltage generation part. A wiring body includes a conductive bar-shaped member having stiffness and contact sockets arranged at two ends of the bar-shaped member. The sockets are fixed to the bar-shaped member using riveting parts. Each socket is electrically connected to a terminal of the high voltage generation part and a terminal of the X-ray tube which function as contact plugs.
