Thermocouple structure and method for manufacturing same

The purpose of the present disclosure is to provide a thermocouple structure and a method for manufacturing the same, said thermocouple structure being less susceptible to measurement temperature deviation resulting from thermocouple drift, being less susceptible to protective tube or protective film fracturing/breaking resulting from deposits adhered to the surface of the protective tube or protective film, and preventing temperature measurement junction movement resulting from thermocouple vibration or the like. A thermocouple structure 100 according to the present disclosure comprises a thermocouple 1 in which one end of a positive electrode wire 1a and one end of a negative electrode wire 1b are joined, and one columnar glass body 2. The positive electrode wire 1a and negative electrode wire 1b, which include a thermocouple junction 1c, are embedded in parallel along the length direction of the columnar glass body 2 so as to only come into contact with each another at the thermocouple junction 1c.
