The invention belongs to the technical field of electronic parts and components, in particular to a method for manufacturing a negative temperature coefficient (NTC) thermosensitive chip for a high-precision temperature sensor, comprising the following steps: (1) preparing NTC thermosensitive semiconductor ceramic powder; (2) forming/sintering into a strip shape; (3) encapsulating by utilizing glass; (4) testing the resistivity; (5) cutting based on the size; and (6) adding terminal electrodes. As for the NTC thermosensitive chip manufactured by the method in the invention, in high-precision temperature measuring application occasions, the precision of the resistance R and the precision of the material constant B are controlled within 0.3%, namely the temperature precision can be controlled at 0.1% DEG C, and the annual drift rate of electric properties ( the resistance R and the material constant B) is less than 0.1% after the chip is utilized in an application circuit, thus the NTC thermosensitive chip can preferably ensure that high-precision resistance adjustments is realized, and has good stability preferably.
