<p>PROBLEM TO BE SOLVED: To reduce the cost of a thermistor having a large constant B and a low resistance by forming a gap between resistor adjusting electrodes by grinding, in a chip type thermistor in the shape of a rectangular parallelepiped having resistance adjusting electrodes formed on at least one surface of the resistor, and terminal electrodes formed on the end parts of the rectangular parallelepiped shape. SOLUTION: On the upper and lower principal surfaces of an NTC thermistor substrate 1 having been burned and having an oxide of an Mu-Co-Cu family metal element for its main ingredient, baked electrodes 2 having Ag for their main ingredients are formed. Next, on the cross direction end surfaces of the NTC thermistor substrate 1 having the baked electrodes 2, terminal electrodes 3, 3 having Ag for their main ingredients are formed. And to form a specified gap 4 in the cross direction approximately-central parts of the electrodes 2, 2 on the upper and lower principal surfaces of the NTC thermistor substrate 1 having these terminal electrodes 3, 3, the electrodes 2, 2 on the upper and lower principal surfaces are ground by a dicing saw. Next, this NTC thermistor substrate 1 is cut into specified dimensions. Consequently, it becomes possible to obtain high-quality chip thermistors.</p> |
