摘要：
An X-ray tube that operates stably over a long period of time is provided.
The X-ray tube includes a cathode, an anode, a cathode hood, a first X-ray transmission window, and an envelope. The anode has an anode target on which a focal point is formed to emit X-rays. The cathode hood has a first opening formed thereon through which X-rays pass. The first X-ray transmission window blocks at least a part of the first opening. The envelope houses the cathode, the anode target, the cathode hood, and the first X-ray transmission window.
