Thermo-sensitive resistor.

摘要

A thermo-sensitive resistor has an electrically insulating substrate (1), a thin-film heating resistor (2,5) formed on the substrate and lead wires (3) electrically connected to the thin-film heating resistor. The resistivity of the thin-film heating resistor (2,5) is adjusted by increasing or decreasing the film thickness of a previously formed base portion (2) by electroplating or electroless plating. In this way the area for heating of the thermo-sensitive resistor can be always constant even if a resistivity adjustment has been performed.
