PROBLEM TO BE SOLVED: To provide a radiation generating device for preventing air bubbles mixed in a refrigerant from being moved by buoyancy or inertia force and radiation from passing through the air bubbles when the device is rotated, and a radiographic device using it.SOLUTION: The radiation generating device includes: a package 16; a radiation tube 11 arranged inside the package 16; a refrigerant 25 arranged between the package 16 and the radiation tube 11; and a cooler 19 connected to the package 16 at an inflow port and an outflow port provided on a bottom part of the package 16. A partition plate 20 for partitioning the inside of the package 16 into a first chamber on the side of the radiation tube 11 and a second chamber on the side of the inflow port leaving an opening is extended upwards from the bottom part of the package 16, an air bubble chamber for accumulating the air bubbles inside the refrigerant 25 is provided on an upper part inside the second chamber, and a projection part projected to the second chamber is provided on an end part on the opening side of the partition plate 20. |
