Abstract

PURPOSE: To effectively manufacture a product having easy setting of conditions in manufacturing steps and desired thermistor characteristics by forming a diffusion preventing layer for preventing mutual diffusion of a thermistor section composition and an insulating ceramic composition between insulating ceramics and a thermistor section.
CONSTITUTION: Paste for a diffusion preventing layer 4 is formed of powder of Y2O5-ZrO2-Al2O3. Then, a sheet for Al2O3 insulating ceramics 3 is coated with paste for the layer 4, and dried. After drying, it is coated with platinum paste for forming electrodes 3, and dried, further coated with paste for forming a thermistor section 2 from above, and dried. On the other hand, the sheet coated with paste for the layer 4 and the platinum paste for forming the electrodes 3, and dried is prepared, these sheets are superposed, and thermally press-bonded under predetermined conditions. Then, it is cut in the size of respective laminated thermistors, and baked at near 1550°C for approx. 2 hours.
