ABSTRACT:
A cathode is formed such that a blackening of the inside wall of the discharge tube due to evaporated material does not occur and good heat transmission occurs. A base member (5) is provided to which a green sintered member (7) is pressed on said base member under high pressure and is then sintered which reduces its size. Soldering or welding is thus accordingly avoided. The volume of the sintered member (7) is significantly smaller than the volume of the base member (5).
