Abstract
In a radiation imaging apparatus, an envelope has a first window for transmitting radiation and is filled with an insulating liquid, and a radiation tube in the envelope has, at a position facing the first window, a second window for transmitting the radiation, and a shielding member. A solid insulating member is arranged between the shielding member and the inner wall of the envelope, and an opening is formed at a position on the insulating member corresponding to the first window. The shortest distance from the shielding member to the first window or the inner wall of the envelope through the opening of the insulating member without the insulating member is made to be longer than the shortest distance from the shielding member to the first window or the inner wall of the envelope through the insulating member, thereby improving withstand voltage performance without reducing an radiation amount.
