<p>PURPOSE:To obtain a thick film thermistor material of low resistance by adding transition metal conductor powder to metal oxide powder, an organic vehicle, glass powder in order to oxidize added metal conductor powder in the process of firing. CONSTITUTION:The thick film thermistor paste composition consists of one kind or more of metal oxide powder selected from among Mn, Co, Ni, Cu, Fe, Cr, one kind or more of transition metal powder selected from among Mn, Co, Ni, Cu, Zn, glass powder and an organic vehicle while containing the transition metal powder 5 to 20wt.%. Further, the composition has a pair of electrodes 2 formed on an insulated substrate 1 and a thermistor layer 3 provided on this insulated substrate 1 so as to be connected to this pair of electrodes 2, and the thermistor 3 consists of a metal oxide to be obtained by firing the thick film thermistor paste composition. Thereby, a thermistor of thick film type structure having low resistance can be obtained.</p> |
