摘要：A filament showing high radiation characteristics and hardly suffering fromdisconnection and film separation is provided by using a high melting point metalcompound such as tantalum carbide or hafnium carbide. For example, as the filament, a
filament comprising a tungsten base material 30, a tantalum or hafnium layer 31 coatingthe tungsten base material 30, and a tantalum or hafnium carbide layer 32 coating thelayer 31 is used. High adhesion is obtained at the interface of the layers of tungsten andtantalum or hafnium.
