ABSTRACT:
The present invention discloses an X-ray tube comprising a vacuum envelope comprising a first tubular part having an X-ray exit window in an opening on a leading end side and an attachment flange on a base end side, and a second tubular part communicating with the inside of the first tubular part and projecting from a peripheral part of the first tubular part; and an electron gun and a target both contained in the vacuum envelope. The electron gun emits an electron beam to the target, the target generates an X-ray in response, and thus generated X-ray is taken out through the X-ray exit window. An exhaust pipe for evacuating the vacuum envelope projects from the peripheral face of the first tubular part. The exhaust pipe is disposed inside a virtual surface covering the periphery of the first tubular part and bridging a periphery of a leading end portion of the first tubular part and a periphery of the attachment flange.
