Abstract
A flexible wired circuit board for temperature measurement that can provide an accurate temperature measurement even when placed in a high-temperature atmosphere and can also be provided at a reduced cost. In the flexible wired circuit board for temperature measurement, a conductor layer formed from a metal foil, such as a stainless foil, having a proportional relation between temperature and specific electric resistance is formed on a base insulating layer. Also, a single thin sensor wiring in a sensor portion exposed from a cover insulating layer is formed into a certain pattern by folding back the sensor wiring in a continuous S-shaped form, such that adjacent parts of the wiring extending in parallel are spaced apart from each other at a predetermined interval in a widthwise direction of the conductor layer. The flexible wired circuit board for temperature measurement thus constructed can prevent occurrence of errors in measured temperature even when used in high-temperature atmosphere, thus achieving accurate measurement of temperature, different from the flexible wired circuit board having the conductor layer comprising a copper foil.
