PURPOSE: A temperature sensor using non-ground thermocouple is provided to enhance the stability and reliability of a product by the preventing of contact failure since insulating resistor in a temperature sensor of a ground thermocouple type is continuously maintained. CONSTITUTION: A temperature sensor(100) using non-ground thermocouple comprises an electrode(10), epoxy, feeding lines(41,42), and a knob(20). The electrode comprises an SUS protecting pipe, a seam line, a temperature sensing unit and an insulating member. The epoxy seals the other end of the SUS protecting pipe. The other ends of two seam lines are protruded to the outside of the epoxy. The feeding lines are electrically connected to the other ends of the protruded two seam lines to supply power. The knob protects the other ends of the two seam lines which have been electrically connected to the epoxy.
