ABSTRACT:
A thermocouple structure capable of measurement of a high temperature with a high accuracy is constituted of a protective pipe made of a heat-resistant ceramic; a pair of wires differing in kind and extending in the protective pipe from one end thereof to the other end thereof in the longitudinal direction thereof in a state of being spaced away from each other; a thin film constituting a temperature-sensing portion, made of a tungsten alloy, disposed on one end portion of said protective pipe, and connected to the wires; and a covering layer made of a heat-resistant ceramic and covering the thin film in such a way as to disallow exterior exposure of the thin film. The protective pipe is made of Si.sub.3 N.sub.4, and a filling member made of a powder mixture of Si.sub.3 N.sub.4 and TiN is filled in the protective pipe. Alternatively, a pair of printed strips differing in kind may be formed as wires in a protective pipe to provide such a thermocouple structure.
