<p>PURPOSE:To obtain an element having thermistor characteristics and varistor characteristics by forming a thick film on an insulating substrate from a mixture of soft magnetic oxide and resistance paste. CONSTITUTION:For example, a thick film is formed on an insulating substrate 1 composed of alumina, zirconia or titania from a mixture of soft magnetic oxide and resistance paste. Subsequently, an electrode pattern 2 is formed to the upper layer of the thick film. In this case, the soft magnetic oxide is constituted of Mn-Cu-Zn type ferrite and the resistance paste is constituted of a ruthenium compound. By this constitution, the resistance of an element reacts with temp. or gas concn. in spite of one element and the element having both of thermistor characteristics and varistor characteristics can be obtained.</p> |
