Abstract

A multilayer thermistor with a positive temperature coefficient is manufactured by stepof forming a green laminate having thermistor green layers and internal electrode layers, stepof heat-treating this laminate at a temperature in the range of from 80 to less than 300° C., stepof performing dry-barrel polishing for the heat-treated green laminate, stepof forming external electrode films on respective end surfaces of this laminate, and stepof firing this laminate together with the individual electrode films. According to this method, a highly reliable multilayer thermistor with a positive temperature coefficient can be stably manufactured.
