Claim:
1. A radiation generating apparatus comprising: an envelope having a first window through which radiation is transmitted; a radiation tube being held within the envelope, and having a target layer, a target supporting window supporting the target layer, and a radiation shielding member having a protruding portion protruding from the target supporting window toward the first window; a thermally conductive member having a higher thermal conductivity than that of the radiation shielding member and connected to the protruding portion of the radiation shielding member; and an insulating fluid filling a space between the envelope and the radiation tube, wherein the target supporting window is arranged in opposition to the first window, and wherein the radiation is transmitted through the target supporting window, and wherein the target supporting window is secured to the thermally conductive member, and wherein the thermally conductive member is connected to the protruding portion of the radiation shielding member at a front side and a rear side with respect to the second window in a tube axis direction.
