Abstract
A thermistor that includes a metal substrate layer, a thermistor thin film formed on the metal substrate layer, and electrode films formed on the thermistor thin film. The metal substrate layer and the electrode films contain a Ag—Pd alloy, and the content of Pd of the Ag—Pd alloy is 10 percent by weight or more.
Claims17
A thermistor comprising:
- a metal substrate layer;
- a thermistor film on the metal substrate layer;
- and
- an electrode film on the thermistor film,
- wherein the metal substrate layer and the electrode film contain a Ag—Pd alloy, and
- a content of Pd of the Ag—Pd alloy is 10 percent by weight or more.
3 more elements
A method for manufacturing a thermistor, the method comprising:
- preparing a carrier film;
- applying a first electrically conductive paste containing a Ag—Pd alloy for a metal substrate layer on the carrier film;
- applying a ceramic paste for a thermistor thin film on the first electrically conductive paste;
- applying a second electrically conductive paste containing a Ag—Pd alloy for an electrode film on the ceramic paste;
- peeling a laminate from the carrier film, the laminate being formed of the first electrically conductive paste containing a Ag—Pd alloy, the ceramic paste, and the second electrically conductive paste containing a Ag—Pd alloy;
- and
- firing the laminate in accordance with a predetermined profile so as to obtain a thermistor element in which the thermistor film is on the metal substrate layer and the electrode film is on the thermistor film,
- wherein a content of Pd of the Ag—Pd alloy is 10 percent by weight or more.
