Abstract
A temperature sensor includes a thermistor element housed in a metal cap and a mineral insulated cable for acquiring signals from said thermistor element wherein the mineral insulated cable employs a ventilation composition that provides stable thermistor element resistance characteristics. Thermistor element is equipped with thermistor section including an oxide semiconductor, and electrode wires extending from thermistor section for acquisition of thermistor signals, and is arranged on the end of mineral insulated cable and housed in metal cap. The mineral insulated cable employs a composition in which electrically conducting core wires connected to electrode wires are insulated and held in a metal outer cylinder by insulating powder filled into the outer cylinder. A ventilation quantity of at least 5×10,ml/(MPa sec) is secured within outer cylinder at normal temperature.
