Temperature Sensor Element

摘要

A temperature sensor element consists of a temperature sensing unit including: a temperature-sensing ceramic unit; first and second electrodes respectively positioned on first and second surface of the temperature-sensing ceramic unit, the second surface opposing the first surface; first and second intermediate electrodes respectively connecting to the first and second electrodes; and first and second lead lines connected to the first and second electrodes via the first and intermediate electrodes, respectively; and a protective unit surrounding the temperature sensing unit, wherein each of the first lead line and the second lead line includes a lead line core coated with a second layer, the lead line core and the second layer being different materials. The lead lines consist of the lead line cores of a metallic material cheaper than the platinum-based metal, which reduces the production cost of the lead lines.
