Summary:An X-ray generating tube includes: an anode including a target (9) and an anode member (43) electrically connected to the target; a cathode including an electron emitting source and a cathode member (41) electrically connected to the electron emitting source; and an insulating tube(110) joined at one end to the anode member and joined at the other end to the cathode member so that the target and the electron emitting portion face each other, in which an inner circumferential conductive film (112) is formed on an inner surface of the insulating tube; an end surface conductive film (113) extends from one edge of the inner circumferential conductive film on the one end side onto a surface of the one end of the insulating tube; and the end surface conductive film is sandwiched between the end surface and the anode member to be electrically connected to the anode member.
