PROBLEM TO BE SOLVED: To provide a thermocouple facilitating connecting work and saving a space even when it is constructed to lead output of two or more pairs of thermocouples to an extension cable. SOLUTION: A connector M1 is provided with male-type and female-type terminals A1, B1 installed at a lead-through end of each strand in a plurality of thermocouples and the front end of an extension cable E. The male-type terminal A1 is provided with an outer cylinder case 1 and a single projection pin 2 inside the outer cylinder case. On the outer circumferential face of the projection pin 2, electrodes 3, 4, 5, 6 individually matching the respective strands of all the pairs of thermocouples are arranged insulatedly along the axial direction of the projection pin. The female-type terminal B1 is fitted inside the outer cylinder case and provided with a cylindrical case 21 arranged around the projection pin for supporting it. The cylindrical case is provided with a single connection hole 21a, and electrodes 23, 24, 25, 26 matching the respective electrodes of the projection pin are arranged on the inner circumferential face of the connection hole 21a. |
