Abstract

Disclosed is a holder for sealing member, in which at least a portion of the holder which comes into contact with the member comprises a sintered body comprising as a main component a non-oxide ceramic of silicon nitride, aluminum nitride, sialon or silicon carbide. By the use of the holder according to this invention, in the hermetic sealing process which is carried out continuously and automatically, an exchange frequency of the holder can be decreased remarkably, and thus a working efficiency on a manufacturing line can be increased. In consequence, the holder according to this invention is industrially very useful, and in particular, it is suitable for the hermetic sealing of the panel pins for cathode ray tubes.
