Abstract
A radiation generating apparatus of the present invention includes an envelopeincluding a first windowallowing radiation to pass; a radiation tubethat is accommodated in the envelope, and includes a second windowallowing radiation to pass, at a position opposite to the first window; a radiation passing holethat is thermally connected to the second windowand communicates with the second window; and a radiation shielding memberprotruding from the second windowtoward the first window. In this apparatus, a thermally conductive memberhaving a higher thermal conductivity than the radiation shielding memberis connected to an outer periphery of the protruding portion of the radiation shielding member. The simple configuration can shield unnecessary radiation, and cool the target, while facilitating reduction in weight.
