<p>PURPOSE:To enable deviation of shrinkage due to firing specific to a ceramic base to be neglected by using a ceramic material for firing at low temperature and firing first and second electrodes and a resistor at a specified temperature simultaneously to one part of one surface or both surfaces of a green sheet base. CONSTITUTION:After mixing a ceramic material for firing at a low temperature, an organic binder, and water, performing dehydration, and vacuum process, molding and extrusion are performed through a dice 18 with a spot-shaped groove to obtain a green sheet base 6. Then, first and second electrodes 7 and 8 and 9 and 10 are formed on one part of one surface or both surfaces of the base 6 and a resistor 11 connected to one part of the electrodes 7 and 8 and 9 and 10 is formed. Furthermore, slit grooves 14 and 15 for division are formed at the base 6 and the base 6 is laser-trimmed to the resistor 11 simultaneously fired by an air environment furnace at a specified temperature to obtain a desired resistance. Also, by coating a corrected part of the resistor with a protection film 16 by a glass paste, sealing for a certain resistance indication is provided and firing at a specified temperature is made.</p> |
