Abstract
Provided are a thermistor and a device using the thermistor by which ohmic contact can be ensured between electrodes formed on a thermistor composition and wiring lines connected to the electrodes, and by which high accuracy temperature detection is possible. A thermistor is provided with a thermistor composition, a pair of electrodes that are formed on the thermistor composition and that contain a noble metal, wires that are joined to the electrodes and that have a passivation film formed on a surface thereof, and a junction material that contains a noble metal oxide which joins the electrodes to the wires.
Claims20
A thermistor, comprising:
- a thermistor composition;
- an electrode portion formed on the thermistor composition and containing a noble metal;
- a wiring bonded to the electrode portion and having an oxide film as a passivation film formed on a surface thereof;
- and
- a bonding material containing a noble metal oxide, disposed at least between the electrode portion and the wiring with ohmic contact to bond the wiring to the electrode portion.
