<p>PROBLEM TO BE SOLVED: To provide a thermistor element of superior thermal responsibility and productivity at low manufacturing cost, and provide a method for manufacturing it. SOLUTION: A thin film thermistor 2 is formed on the entire surface of a ceramic substrate 1. After a pair of internal electrodes 3 are formed on the thin film thermistor 2, an insulation inorganic material layer 4 is formed so as to cover the internal electrodes 3 and the exposed thin film thermistor 2. On the insulation inorganic material layer 4 on the upper side of each internal electrode 3, a conductive paste which contains metal powder and an inorganic bonding material is applied and burned so as to have an area smaller than the internal electrode 3 by screen printing, etc., to form an external electrode 5. Because of burning (baking) of this external electrode 5, the insulation inorganic material layer 4 sandwiched between the external electrode 5 and the internal electrodes 3 is absorbed by the external electrode 5, and a current flows through the external electrode 5 and the internal electrode 3. Then the substrate is cut into chip shapes, to obtain a plurality of thermistor elements.</p> |
