Abstract

An inorganic insulating member comprises a conductor containing Ni or Ni alloy at least in its outer surface, an oxide layer of Ni or Ni alloy formed through oxidation treatment of the outer surface of the conductor, and an insulating inorganic compound layer which is formed on the oxide layer of Ni or Ni alloy. The insulating inorganic compound is separated only with difficulty and the inorganic insulating member is improved in heat resistance and insulability.
