Abstract
PURPOSE:To prevent the exfoliation of the electron radiating substance by manufacturing electrode coils having different inner diameters and holding an electrode core wire with the samll inner diameter part and the inserting electron radiating substance into the large inner diameter part and allowing the coil end part in the large inner diameter part to be contacted under pressure with in the direction of the core wire. CONSTITUTION:A coil 5 has the small inner diamter part 5a having the inner diameter equal to the outer diameter of an electrode core wire 6 and the large inner diameter part 5b having the larger inner diameter than the outer diameter of the electrode core wire 6. The electrode core wire 6 is inserted into the coil 5, and holding of this electride core wire 6 is performed with the small inner diameter part 5a of the coil 5. Electron radiating substance 7 is inserted into the gap between the electrode core wire 6 and the large inner diameter part 5b, and the coil end part 5c is contacted under pressure with the core wire, and the exfoliation of the electron radiating substance 7 is prevented.
