A thermocouple sensor and a production method therefor, wherein the thermocouple sensor has a thermocouple body and a stainless steel pipe, wiring metal ends are arranged at both ends of the thermocouple body, there is an opening at one end of the stainless steel pipe and a pore at another end, the thermocouple body inserts into the stainless steel pipe from the opening, and one of the wiring metal ends passes through the pore and is welded with the stainless steel pipe at the pore. The stainless steel pipe is directly changed from a heat transfer component into a heat sensing component, so that after the stainless steel pipe is in contact with the heat, the heat is not required to be transferred to a heat conducting medium and subsequently to the thermocouple.
