ABSTRACT:
An electrode for connecting an external electric wire to a body heated to a high temperature includes a high temperature side electrode made of a conductor connected to the heated body, and a low temperature side electrode connected at a first end thereof to the high temperature side electrode and at a second end thereof to the external electric wire. The low temperature side electrode is formed of a conductor covered by an insulating material with the conductor of the low temperature side electrode being made of a material having a conduction resistance smaller than that of the conductor of the high temperature side electrode. Thus, as the conductor of the low temperature side electrode has a smaller conduction resistance than the conductor of the high temperature side electrode, an increase in a resistance value is reduced even when the conductor of the low temperature side electrode is extended to lower the temperature at a connection to an external electric wire.
