    Abstract: An emitter for an X-ray tube device is configured to irradiate an anode with electrons for X-ray emission. The emitter includes an electron emission portion to be heated by an electric current, a current application leg for supplying the electric current to the electron emission portion, a support leg, a current application leg fixing portion for supporting the current application leg and supplying the electric current to the current application leg, and a support leg fixing portion for supporting the support leg. At least one of materials and shapes are different between the current application leg fixing portion and the support leg fixing portion so that a difference in an amount of thermal deformation between the current application leg and the support leg in a direction vertical to the electron emission portion is reduced when the electron emission portion is heated.
